Thought I would share a problem that I encountered over the weekend. I upgraded my laptop that has a Vista operating system to the new Winddows 7 upgrade for Vista (which is recommended). After downloading Windows 7, my Photoshop CS4 program could no longer download my photos from my memory card. An error window kept opening saying I had low disk space and could not retrieve the photos. I spent a great deal of time on the phone with Microsoft (went through 3 technicians) and with Adobe. Each one says it is the others problem. Anyway, my laptop is now with my computer tech and this weekend he will empty everything and re-install Vista, Windows 7 and CS4 in that order. He thinks that will solve the problem. Will update everyone after I get it back, but wanted to alert others contemplating upgrading Vista to Windows 7 that it could be a problem.
I upgraded my main desktop from vista 64 to win7 64 and didn't have any problems. Although, they always recommend a clean install when upgrading the OS instead of upgrade in place...I just figured I could take an hour or so to upgrade in place and if I had problems, then I'd do the full install and reinstall all of my software. Sound like I got lucky and you didn't.

Ken, have you tried to reset PS to standard settings? There is a key combination that you have to press while starting the program. I don't know the one for Windows but it should be easy to find on Google.
with a W7 "upgrade" cd this is not a full install cd only a clean installed did it. upgrade had trouble finding drivers even fresh download for w7 on a media could not be found so I followed these steps for clean install with the upgrade cd from here & it work 100%
