Apologies if this in the wrong place... I'm having problems with an app using the TiVo Beacon API. When using the API on a machine with TiVo Desktop (2.1) running, the Beacon API window (class=TmrWindowClass) in TiVoBeaconAPI.dll is returning FALSE to the WM_QUERYENDSESSION message. This tells Windows NOT to shut down, and also prevents my app from shutting down automatically when Windows is shutting down. If anyone knows of a fix, or a way to directly contact TiVo developers, I'd be very grateful! Thanks in advance. TiVoBeaconAPI.dll version is 18.104.22.16810.
