I managed to get Windows 7 running on my 27" iMac not long ago but experience terrible performance on the OS X side (everything was crashing, colours were going haywire, slow performance) so I decided to delete Windows 7 and everything went back to normal. But now of course I need Windows 7 for something, so I have a few questions about making my experience better this time around; How do I get rid of that colour banding issue? Does the Magic Mouse & Keyboard still take awhile to be recognised by windows? Is there anyway to stop Windows 7 giving me all those problems I was experiencing before? Thanks.
