I've just encountered a new problem in Photoshop7...something about a scratch disk and performance of the program.  I started getting a message a couple of days ago when I open PS.  Something about scratch disk being on the same drive as windows and that I should move it to another drive if possible so the performance wouldn't be compromised.  So I moved it to the D drive and PS is soooooo slow for me now.  I moved it back to where it was, but still the program is slow moving.  I've never even heard of a scratch disk until this came up.  Why is this happening and can I fix the problem?  I think it started around the time I had a particularly big render in Poser and the message came up in Poser that Window's was doing something with the virtual memory.  Could this have caused it and again, can I fix it?  Any help would be appreciated.

My idea of rebooting is kicking somebody in the butt twice!
