Well... :) actually, uhm... 
I got to admit, I'm not up to par with how global exception
handlers would work for any dll in order to make sure it's
closed before the eu error pop-up console window no matter what the
dll is used for. I guess I need enlightment in that department.
It's just kind of hard for me to see and understand why Euphoria
doesn't free up ANY and ALL user created stuff( ie: allocated memory, 
loaded
dlls, etc.) before Euphoria finally shows what Euphoria related user
error in the console window. But I do realise and respect that you, 
Robert, that you most likely see that it wouldn't be feasible 
to change up alot of internal Euhporia code just to fit that one need. 

But the fact remains that my dll is still active when the Euhporia
Error console window is activated by Euhporia itself and then the dll
will close after you hit return to exit the Euhporia error window.
I'm guessing there is no arguement on that note.

So if you go with this global exception handler thing, would I be
able to call a Euphoria function from my c coded dll to determine
that Euhporia has quit do to an error? If that's how it works,
then I would know I can shutdown my dll so that the DirectDraw 
Fullscreen surfaces would be released and freed. Then
Euhporia/Exotica users could smoothly see that the DirectX stuff
is now freed and now back to there desktop with the Euphoria
error console window sitting right there waiting to be read.
