I installed parallels on macbook using os 10.5.1 and bootcamp with vista ultimate, after i found out that i have to activate vista again then i uninstall the parallels on mac and also parallels tool on windows. After that, when boot from windows disk my mouse and keyboard don't work properly, mouse move very slow and keyboard have to type very slow, then i reinstall bootcamp then they work fine, until i restart the computer then it happens again because vista cannot shutdown properly. Any idea how to fix this?
