I've asked about this before, and I think I was told to update my driver...but has anyone experienced occassional loss of scroll mouse (wheel) functionality while modifying objects?

Often, I will be modifying something and the zoom function of my wheel mouse button goes AWOL. Instead of zooming - like it normally does - it scrolls my screen up and down, and usually in large jumps. This usually makes everything move out of my screen range leaving me looking at a blank white screen. I've noticed it most while working in 3D views, although today it is happening in a plan view. I find if I close the view and reopen it, the functionality returns. But, it is quite annoying, as I often have to re-execute the modification process.

Driver updates don't seem to affect this, though it's not like I update my mouse driver regularly. Anyone else have this?
