Thanks for everyone's help. The problem was a CLEAR EVENTS was seemingly being fired but the debugger kept returning to my READ EVENTS line. This obviously confused the hell out of me so I thought the debugger was not really working. I was also trying to use BINDEVENTS to fire some shutdown code in the top level form's PostUnload method by binding this method to the Unload event. It was not firing. When I removed the BINDEVENTS, and just put the code in the Unload, the shutdown code started firing. However, to get the app to totall shutdown, I had to close the debugger. The debugger just would not move off my READ EVENTS for some reason. I have either found an anomoly or did not do something just right. At least all now works as expected. I'll try to hammer out some repro code, but I am not very hopeful.
