Answer 1

You need to capture the exception within the thread itself, and "transfer" the exception to the main thread.

Wrap your thread code in try...except , grab the exception, and stuff it inside a variable that the main thread can see. The main thread should be looping + idling, and when the main thread sees that variable contains an exception, reraise the exception.
