pq12249.st PRESSING THE WINDOWS KEY THE CAUSES THE NUL MNEMONIC FOR 
                    A CWTOGGLEBUTTON TO BE PROCESSED


Create a window with a togglebutton that has a mnemonic on it. Test it and press 
Windows key.  Pressing this key causes the KeyPressMask event handler 
(CwBasicWidget>>#keyPress:clientData:callData:) to get invoked.  This
method then calls a method to process mnemonics and accelerators.  Eventually 
a check is made to determine if the toggle button has a mnenmonic.  This 
evaluates to true because xmNmnemonic is notNil (it is set to Nul).
