Random freeze when calling Stop() (not especially after the end of the movie) #12

Closed Ceylo closed 13 years ago

Ceylo commented 13 years ago

Here the sample prog is freezed on Stop() (because of a dead lock) It's quite hard to get this freeze but it happens in maybe 1% cases..

Does not seem to happen anymore with new implementation. Closing.
