Thanks for opening this thread! I can't figure out why this is happening! I use VMware Fusion, on my 13.3" MacBook with Leopard, to run Windows. I have Age of Empire II installed to Windows XP, but when I play it, the graphics look very weak, the resolution wont set correctly, and the mouse is very laggy. I use a retractable-cord Rocketfish mouse from Best Buy. Its a compact travel mouse, and have very fine response time in the OS X environment and in windows, but the full-screen game seems to mess it all up and make it slow to respond, no matter what the Windows mouse speed setting is. Anyone have any ideas or similar problems using VMware Fusion?
