I have Windows XP Pro SP3 32-bit. I am able to open a single document without problems. However, if I try to open another PDF, a Reader window opens that is blank, my computer freezes for about 10 seconds, and the entire screen flickers about every 3 seconds. Once this is over, the blank window remains and I can then close it. After closing it, I can continue working with the first PDF without any problems. This is the first time I have experienced this, and it happened shortly after the latest Adobe Reader update. Any ideas on what is going on and how I can fix it? I have already tried uninstalling everything Adobe in Add/Remove programs and reinstalling, but I'm still having the same problem.
