FWIW, I don't necessarily see the crash immediately upon hitting OK: I mayb have to do something to force another re-layout. Ctrl+A does the trick. Under the debugger, it didn't seem to always crash in the same place - that might depend on the specific type of staff you add. The nature of the crash makes it look like memory corruption to me, but I could be wrong.
