Strange temp files in PS CS2

Ever since I got PS CS2 I've been finding a bug. I send something from Bridge to Camera RAW (all I shoot is RAW) to Photoshop. I work on it in Photoshop and try to Save As the work as a .psd file. At this point PS interrupts with a message that says something like, "You cannot Save this file. The file is already open." Then if I go back to Bridge and look through the folder I will find a temp file. If I delete that temp file I can go back into PS and Save As my image file like I wanted too. The temp file name has nothing to do with the original Canon 20D RAW file name, nor the name I want to give it later. I didn't make it nor understand where it came from. One of those temp files, currently living in my recycle Bin is named ~PSE728.tmp

As I said I'm using a Canon 20D and use Photoshop Elements 3.0 to download the file from my card reader to the computer. The computer is a conventional Windows type with an AMD 1700 processor and a gig of memory. The C:\ hard drive is 80 gig and is about half full. I have a collection of the usual suspects with software. WORD, Firefox, and this and that. I have been using Photoshop CS for the last 18 months without any of this kind of problem.

Comments?

That's why I have to look at another file in the Bridge when I get that message. Then I can save my file.

Now, I'll just kill the temp file and be done with it. Less of a fuss.

See the Bridge forums - this appears to be a problem with Bridge (timing related, so it doesn't always happen).

I've been running into the "file already in use..." error working on a large psd file. I tried clearing the history with no effect. After seeing this thread, I switched to Bridge and changed its view from the directory I was using to one I wasn't. Then Photoshop would save the file without fuss (and do it nearly instantly instead of present a slow status bar as it did before the error).

Bridge bites.
