sounds good :)

BTW: another point against the userdef stuff: with most AESes (i don't  
know for XaAES), userdraw subroutines are not allowed to call AES  
functions (AES is not re-entrant). That may lead the system to crash.

About the proposal:

I'd prefer the following:

wind_open(0,dummy,dummy,dummy,dummy);

This will ask the AES to send WM_REDRAW message to window handle 0 instead  
of drawing the desktop formular. The window dimensions (dummy) shall not  
be taken into account by the AES. That window shall not be topped when a  
mouse event occurs on it (WF_BEVENT/BEVENT_WORK feature))

wind_close(0); or wind_set(WF_NEWDESK); shall remove that desktop-window.

Note that there are no wind_create()/wind_delete() call for that  
particular window.

Last point: other wind_xxx() functions shall be ready to manage the case  
'window_handle == 0' (i think it's already ok).

best regards,
Arnaud.
