The only events you should ever release are ones that you create, copy or retain; all events passed to your handlers are released by the OS after your handler returns. > Can it be a release of something else than an event that could cause this crash? Yes; Specifically Core Foundation (CF) objects. Look for CFRelease's and make sure the object they're releasing were created, copied or retained by you. If they were passed to you or came from a "get" function then you should only release them if you retained them at some point. -- Enjoy, George Warner, Schizophrenic Optimization Scientist Apple Developer Technical Support (DTS)
