vb (6.0) application hangs when press the stop debugging

hi,

My vb 6.0 application uses video streaming from (USB) Camera.

Run the application (debug) - do not start Camera - stop debugging - result -> OK.

Run the application (debug) - start Camera - stop debugging - result -> hangs

Run the application (debug) - start Camera - stop Camera -> stop debugging - result -> hangs


Run the application (debug) - start Camera -> close application using "Close" button on application -> result -> OK

Run the application (debug) - start Camera -> stop Camera -> close application using "Close" button on application -> result -> OK

what could be the problem?

advance thanks

pmk
