Hi Dov --
I was obviously mistaken re: tilde files on Windows (the drawbacks of a quick search). Apologies.
As for why I'd want to hide them... see my reply to Bob Levine, but ALSO -- Illustrator doesn't create (or at least show) them. Photoshop doesn't. Premiere, I believe, has the decency to tuck them into another folder.
My point is that they can do their job without mucking up the GUI -- and also that after 6 (6.5) versions of CS, there are a number of things that still don't jibe between the various components (another example: closing a project in Premiere closes the application -- and THAT'S absolutely a Windows-like thing which I hate).
I didn't intend to start a flame war. I apologize for this going on as long as it has -- all I originally wanted to do was see if there was a way to hide the files. I got carried away.
