[AD] win32 allegro_exit() blocks on non-active Window

[aj <aj@xxxxxxxxxx>]

when i call allegro_exit()  it blocks until its made the active window.

by the time i have started to exit my program, the window disappears and 
there is still some work to be done, but from the users point of view the 
window is gone and therefore the program shut (in the users 
view).....   now the user clicks on some other Windows program,  but the 
allegro program continues until it gets to allegro_exit()  where it blocks 
until its made the active window again. (by clicking its task in the task 
bar).

why must it be the active window ?




i have no idea what the real reason for it is, but here is what i have 
found so far...

in   exit_directx_window()    in /allegro/src/win/wwnd.c

i found this:

/* destroy the window: we cannot directly use
* DestroyWindow() because we are not running
* in the same thread as that of the window.
*/

PostMessage(allegro_wnd, msg_suicide, 0, 0);

/* wait until the window thread ends */
WaitForSingleObject(wnd_thread, INFINITE);

-----

idea:    would using  win32::PostThreadMessage()  fix my problem ?

does the current code block because the allegro_wnd is switched out and 
therefore not processing its messages ?
or does Windows not post the message into the allegro_wnd's queue while its 
not an active window ?

-------------

why does  code in    exit_directx_window()    in /allegro/src/win/wwnd.c

attempt to shutdown the allegro_wnd  when i have already removed it by 
calling set_gfx_mode(TEXT)
could this  PostMessage()  be avoided by checking if the allegro_wnd  has 
been shutdown already by a call to set_gfx_mode(TEXT)

??  does set_gfx_mode(TEXT)  attempt to  DestroyWindow()   if not, why not ?
