Mike,
I'm reading through the code to see if I can find anything before I send you another debug dongle. The output I got from the last one was pretty mysterious so I decided to do some code inspection and analyze the different threads running when the problem occurs before adding more debug traces. While I have you, can you tell me what the command you use to start mvpmc is? Anything might provide a clue to help me solve this.
Cheers...
Sergio
