it's just going into the debugger with no visible source stack trace - it was just running the default "start new instance" under debug - I'm now "running" the release (without debugger) and I haven't seen any complaint (do you have a log file where messages like
HEAP[mojo.exe]: HEAP: Free Heap block 20efa68 modified at 20efa90 after it was freed
would go when starting from windows normally ?)
