One possibility I can think of is that perhaps you forgot to declare a=20 CompleteSystemSetup object at the top of your main() function... your mai= n()=20 should look something like this: int main(int argc, char ** argv) { muscle::CompleteSetupSystem css; [...rest of program here...] } Another possibility is that maybe you need to declare your QApplication o= bject=20 earlier on... perhaps it does some behind-the-scenes setup that QMutex=20 requires. Let me know if neither of those are it! Jeremy
