Reversing this one change in server/window.c allows my application to run with
the current git.

- struct window *win = get_desktop_window( current, 1 );
+ struct window *win = get_desktop_window( current, req->force );
if (win) reply->handle = win->handle;

The trace show that a 32bit window is created for the 16 bit application if
req-force is used and shortly followed by a page fault. With req->force replaced
by 1 a 16 bit window is created and things function.

There is a problem with borland's easywin lib and it will not run on win98 or
higher with the same type page fault.
