Photoshop :: CS3 Startup Error - Unable To Locate...

I get the following message almost, but not every, time that I start Photoshop.

b This application has failed to start because vfzcore.dll was not found. Re-installing the application may fix this problem.

I have tried reinstalling Photoshop. But this does not help. I often also get a windows error after photoshop is closed saying that it did not shut down properly.

I suspect that the vfzcore.dll error is due to some 3rd party plug-in. But does anyone have any ideas? These error do not appear to affect the performance of photoshop that I can tell. Everything that I use works fine and it never bombs off (except after closing the program out). But having to hit "OK" at the error dialog every time the program starts up is annoying.
