stop xchange defaulting to format tab when minimising window?

[femtynyl]

Hi,
I'm using the pdf xchange version and I'm having a problem where the programme defaults to the format tab everytime i minimise the window. Is there a way to turn this off? I don't use the format tab and find it useless. The format tab is coloured in yellow if that helps.

There were a couple of threads from about four-five years ago which raised this topic but i dont know if anything ever came from those.

Thanks
