Yes - our Viewer should be working properly and without errors on Win 8.
Can you please check which build of the Viewer you are using (go to Help -> About inside the Viewer) - and if it's not the latest 2.5.210 try downloading and installing it from here: www.tracker-software.com/PDFXVwer.zip
Also have you tried to perform an uninstall, reboot, reinstall, reboot sequence for our Viewer since this problem started appearing?
