Sporadic Mouse Hang-ups

I have been having sporadic mouse hang-ups for some time now. They usually only happen when I am minimizing, maximising, or attempting to scroll a window and mostly happen on the Internet though it happens elsewhere as well, depending on what I am doing.
I am running a AMDk6-2 475 clocked at 95X5. 96 megs of ram, an 8mb Intel 740 AGP display.
Mouse is a Logitech M34 series. Updating drivers does not seem to help.
