Wiimote: Fixed the hanging for real. Any call to a function in the wxDialog frame class while the main thread is in a WaitForSingleObject() loop or any other loop will hang the g_pReadThread execution until sometime after that loop has ended. So we must wait for pReadThread to stop from the wxDialog with a timer, we can not use any loop in the main thread to wait for it to stop.
