CPQ glitch. Getting really pissed.

It happened to me once (in normal mode if I remember correctly) and it was mildly annoying but I really didn't think much of the stuff going past the corner. That problem has been happening to me for over a year now (it has gotten better by now, back then it occurred at my first attempt to log on so I always had to log on twice).

Edit: Also, I don't use vista, I use windows XP.
