oh, sure. It turned out there was a program running in the background that was incompatible with windows aero. I noticed this when i restarted the computer once and there was an icon in my toolbar that windows aero wasn't compatible with a program that was running, so i clicked on it and it told me the program (qttask, which is quick time i think), and i went to the task manager and found the program in the processes list, and ended it. After that, glass works great now.
