Greetings, using Search, I couldn't find an answer to this question: How do I disable Parallels setting Win XP's screen resolution to the size of the window? My problem is that I am on a MacBook Pro with a maximum screen height of 900. I want to run Win XP at 1280x1024 (requiring a vertical scroll bar, of course in the Parallels window) to run this crappy, custom software (don't ask, but it is the only reason I need WIndows) that will not run, unless the resolution is set to 1280x1024. I select the resolution in WinXP, it tries to change, then reverts immediately back to whatever size my Parallels window is. Any suggestions? I've messed about with the Custom Screen Resolutions to no avail.
