Using Beta2 of FF3.
When I use FF3 to manipulate a file from with Photoshop, and apply the changes, and then then immediately start FF3 back up, I get an error window titled "Filter Forge plugin - Exception caught at thread 00000440 'Application'"
After I click "OK" on that one, Adobe Photoshop CS5 throws it's own relating to a program error.
I've included a screen shot containing both error messages.
This doesn't happen to me at all in FF2, doesn't happen in FF3b1 and, frustratingly, doesn't happen to me every time in FF3b2. However, I think because of the actual issue being named in the error message this is a timer bug of some sort (yeah, I'm sure I'm misusing jargon here, lol)
