Windows seems to function correctly until I try to type in any program, including changing folder names on the desktop. When I type the first letter--any letter--the Windows OS becomes unresponsive. I can move the cursor on the screen, but neither keystrokes nor mouse-clicks will fix produce any results. I am running XP Professional from a Boot Camp partition in Parallels 5. The problem developed in Parallels 4 and I hoped that the new version would solve the problem. I don't have the problem if I boot natively under Boot Camp.
