Yeah, happens in 32 as well. Buzz ran for all of about ten seconds before this happened...
I have a feeling that it often happens when I interact with a menu (you can see the Buzz open file menu at top left of the capture) but it seems to be fairly random. I also think it's connected to my interaction with the program as I accidentally left a debug session (64 bit) running in the background for maybe half an hour or so after I got sidetracked and the exception didn't happen.
