Hi, no I'm not saying this started with office 2010, that was just an example of one of the programs that this happened with. I have tried changing the magnification at the bottom right of my screen but it is only the pop-up windows that this affects the rest of my computer is fine. I thought it may be a compatibility issue with older programs but as it happened with office 2010 I don't think that is the case. As I said it seem to go both ways. When I start my adobe elements program the update checker comes up bigger than the screen. I had one program were the pop-up was so big I could not click on any of the buttons or move the window, I had to re-boot the computer.
