Each time I enter full scree in 98SE I get a small window in the middle of my screen. I can go into Control Panels and resize it each time using Display>Settings. Is there a way where the size can be locked in for future use - same as works for XP?
Peculiar. I assume you have the Parallels video driver installed? Works fine here (build 1920, Win 98 SE, OS X 10.4.8 on Mac Mini): it goes from 1024x768 to 1600x1200 every time I switch to full-screen (though the cute animation is bit jerky...).
I just noticed that this is controlled by the Parallels preferences: Preferences -> User Interface. Perhaps your prefs were reset for some reason...? That or a genuine bug!
