When the program is suspended, choose the thread you wish to disable, right-click, and choose Disable thread from the pop-up menu. The thread will show a status of (disabled) and it will not run until enabled. You may wish to disable threads that must complete before another thread takes some action. By disabling the other thread you can step through the current thread.
To enable a thread that you have disabled, right-click it and choose Enable thread from the pop-up menu. The thread will return to (suspended) status.
