I have a similar problem to the one Jay had, but I don't use Photoshop. If
I try and scroll down one particular (large) folder of pictures, and if I
have the view by "Thumbnails" option on, likely as not the entire folder
will suddenly disappear from the screen.

That's the problem precisely, Bob. Does Windows Explorer shut down
completely when this happens?

The work-around may be the same. You might try shorter folder (not file)
names?
