Hmm.  I thought more parameters were added, rather than removed, as a 
general rule, in Laurent's reworking of the code.  But I didn't look at 
the code for mouse movement and click handlers, so you probably have the 
straight scoop.

Glad this one is straightforward to fix, anyway.

Sounds strange.  And does this new/DESTROY happen frequently only after 
the main window disappears, or all through the execution of the code? 
And I don't know if DC's are subject to the cascading destruction of 
their parent window?

I agree this would be an appropriate path.  Although I haven't used TGL, 
I think it is a significant application for Win32::GUI, and I wouldn't 
want to break it with a new release of Win32::GUI, even if it means a 
little delay.
