can't hold down keyboard and move mouse

[mmoylan]

I recently made myself a lite verison of windows using nLite I took out a lot of things but I have a problem now. I use a ps/2 mouse and keyboard and now when I try to hold down on ctrl or shift while using the mouse the mouse slows down to being almost unresponsive. This makes it nearly impossible to select multiple items using the mouse. Has anyone else experinced problems like this or what I may have removed to cause this problem?
