Tabs broken after recent update

Post by agentsanders »

Good morning. IT pushed an update to PDF Xchange Pro 10.7.5.403 today, which appears to have broken my tab behavior settings.

Pre update my default settings were to always open files in a new tab. Didn't matter where I opened from, it opened as a new tab. I often compare PDF's side by side, and could freely move individual tabs between different windows.

Post update tabs no longer work as expected. I still see the tab on the ribbon/toolbar, however, new documents are opened in a new window and I am unable to manually move tabs between windows. If I open the new document from use command File → Open then it IS opened as a new tab and I CAN then freely move to a separate window and move the tabs between windows. If I open a document by double clicking in explorer after having mulitple tabs already it still opens in a new window and I cannot dock said tab with the others, nor move the working tabs to that new window.

I've confirmed that both the "restore last session..." , "open each document in a new window", and "single document mode" settings are all disabled. The "open new document" and "open related document" dropdowns are both set to "in new tab" behavior. I haven't changed any of these settings, and again, this all worked as desired and expected yesterday prior to updating. I have PDF-XChange Editor as the defulat program for PDF's. I believe that opening a pdf from anywhere other than within the app is causing an entirely separate instance of the app to be started instead of within the existing instance.

After perusing tab related topics from the forum I found the following threads that describe exactly the behavior I am seeing:
viewtopic.php?t=38425&hilit=Tab
viewtopic.php?t=28223
Problem is, both are referencing the use of a portable version of the app, and I'm pretty sure I'm not, nor have been, using the portable version, as there is a clear installation file path (C:\Program Files\Tracker Software\PDF Editor) and am able to run OCR on files have active intigration plugins. Maybe I'm wrong though.

I'm going to try and get someone from IT (I don't have admin access) to do a full re-install but don't know how long it will be before they respond to my ticket.

Is there a definitive way to confirm that I am not somehow using the portable version?
Does anyone know how to fix this so it works the way it did before?
If there's no fix can the the update be rolled back?

Hi agentsanders,

Please note that, as long as you don't have cusomized settings you want to keep, you can always reset the software settings via File -> Manage Settings -> Reset Settings - that may resolve the issue right away.

You can check if you're using the portable version in the Help -> About window.

Previous installers that your license covered are available in your account while you have active maintenance, and for 90 days after maintenance expires.

I hope that helps.

Experiencing this as well. I've gone into Preferences>General>Tabs and Windows to ensure the 'Open each new document in a new window' is not checked. However, pdfs are still opening in new windows instead of a new tab. I've also tried resetting settings via Manage Settings>Reset Settings. I wanted to note when trying to Apply the preferences by clicking 'Apply' nothing happens. I'm not sure if this is an expected behavior, but no acknowledgement is received that changes have been applied.

Please advise is I am missing any steps. Would really like new pdfs to just open in a new tab versus a new window each time.

Thank you,
Christine

I am also expirencing this issue. After fully re-setting my settings (via File -> Manage Settings -> Reset Settings) as mentioned, the issue persists.

Hello, All

I cannot help but notice that all 3 of you are contacting us from the same parent company.
In looking through our history with your company, my colleague Dimitar discovered what may be the culprit. It seems that one of your system administrators may have pushed a registry key explicitly intended to force this situation:
image002.jpg
Can you please ask them to try reverting this (effectively, change the data string value here:
  • Computer\HKEY_CLASSES_ROOT\PDFXEdit.PDF\shell\open\command
Back to its default value of:
  • "C:\Program Files\Tracker Software\PDF Editor\PDFXEdit.exe" "%1"
This may resolve the issue for you after a system restart.

If that (and a system restart) does not fix the issue for you, than I will need to ask again for the same suggested to your colleague by email on the 11th.
Can I first ask that you update the software, since your initial report states you are running version 10.7.5, and there has been a new release since then.

Following that, if the issue persists, could I ask you to please record a video of the process, starting when you have the preferences window opened, so we can see the "single document mode" settings as they are configured on your end before the issue happens.
Kind regards,

Hi I am having the exact same issues, but I don't believe I am at the same parent company as the other three users. Can you please assist a solution? I have tried all of their solutions as well.

Hi, something123

the solution for the others was to get their IT to change the setting that was forced.

If you are not a part of that you should not be seeing the same issue as it was not a bug but a specific setting that was set.

What you can try is to export your settings to file as a back up and to send to us, then reset the settings to factory defaults and let us know if that resolves the issue.

You both export, import and reset settings via the Manage Settings under the File menu:

I am keen to hear if that helps.

[File removed by admin - as it was not a settings export, and may have been sensitive information]

Attached is the exported settings. I have previously cleared my settings to default and it did not work. Similar to the others, the apply button was not working correctly and would seem to either not save the settings or completely ignore it. I can attach a file of this occurring as well.

Hello, something123

Sorry, just to clarify, I checked the account data, and your forum address is from the same domain as the others, so you should indeed be part of the same company. Please do reach out to your IT team.. Including email contact, I believe you are the 6th individual I have now seen report this issue form that company, so you may want to inform your IT team of this post, and have them put out a notice/request to everyone in the company asking if they experience this issue, since the items I mentioned earlier are very likely related, if not the root cause for everyone in your organization experiencing the issue.

If the issue persists after they have reviewed this, please have your IT team contact Support@PDF-XChange.com so that we can more easily and openly identify the organization and hopefully ensure everyone is in the loop.

Kind regards,
