I have been using a PC USB keyboard with Windows XP in Parallels 4.0. Up until now, it has worked fine. Two days ago, I installed Windows XP Service Pack 3. The next time I went to use the PC keyboard, it would act like I was holding down the first key I pressed. I could only stop the continuously repeating keystroke by stopping the process completely. I uninstalled SP3, but it is still happening in SP2. I uninstalled and reinstalled Parallels Tools, and that did not help either. I need the PC keyboard for dialing into work. I use an IBM iSeries (formerly known as AS/400), and make much use of the high-number function keys, insert, etc. Using the Send Key option is quite cumbersome. Please help!
