First up, whenever PS is giving you problems, delete/reset your preferences.
To do that, hold down the Alt, Ctrl, and Shift keys as Photoshop is starting.
A dialog box will appear asking if you wish to delete the preferences file..click yes.

Next (and what I think might be giving you problems) is to disable the startup scripts.
You do that by opening Bridge and going to Edit> Preferences> Startup Scripts, and click on “Disable All”.
I also find it a VERY good idea to disable Version Cue.
Photoshop>Edit>Preferences>File Handling, and uncheck “Enable Version Cue” (PS will love you for that).

 Finally make sure your AutoFX plugin(s) are up to date for use in PSCS3.
I remember they caused a lot of problems with the last version of Photoshop (CS2), and had to have update fixes.
