I setup a MidiTrk pointing to a DrumMap. I then added a TTS-1 to provide the drum instrument and updated the drum map to point to that instance of the TTS-1. Cleaning things up later on, I removed that TTS-1 from the synth browser and saved the file. I didn't think about updating the drum-map so it was still pointing at the deleted TTS-1. I saved the file.
Selecting the track causes a CTD with an exception not handled error. Most of the error msg is blocked by subsequent msgs about the program being closed and the Fault Reporter prompts. Loading the saved file, re-creates the CTD when selecting that track, though the project loads OK.
Which reminds me, the Fault Reporter does not appear to be working either. It almost always times out with a 'No connection' error . I've only seen about 1 or 2 Fault msgs get sent over the course of the 10 or so CTD's I've had this month.
