Cursor problems caused by Photoshop

Has anybody had problems with Photoshop interfering with cursor processing in other apps ? It often happens when you have it on in the background. I have seen it in several apps and even in the FInder. It comes and goes, so it's not always there. It's especially annoying when you work with apps relying heavily on cursors changing and giving instructions to the user. For the most part, it seem to go away if you turn off Photoshop, so I'm pretty sure it's caused by Photoshop.
