Windows 7 & Age of Empires II: works but not quite?
have you tried modifying the shortcut to use compatibility modes for previous windows versions?
I don't think its Windows 7 actually. The scrolling glitch is something that happened back in the XP days as well.
Do you have a Zune? A lot of people who have experienced the scrolling glitch have had Zunes, and after uninstalling the Zune drivers and software the problem has been fixed.
Another fix that used to work for people was powering off the computer, unplugging all peripherals, then once you get to the desktop/login screen, plug them all back in. You might try that as well.
I have found a fix for this:
I did not have to uninstall zune to fix it either.
I believe that it is one of the Zune processes that is causing the scrolling problem. If you don't start zune(and kill all processes) Age of Empires II will work.
