- We use a dirty hack here to disable all application windows (which we
- must do because otherwise the calls to wxYield() could lead to some very
- unexpected reentrancies in the users code) but to avoid losing
- focus/activation entirely when the child process terminates which would
- happen if we simply disabled everything using wxWindowDisabler. Indeed,
- remember that Windows will never activate a disabled window and when the
- last childs window is closed and Windows looks for a window to activate
- all our windows are still disabled. There is no way to enable them in
- time because we don't know when the childs windows are going to be
- closed, so the solution we use here is to keep one special tiny frame
- enabled all the time. Then when the child terminates it will get
- activated and when we close it below -- after reenabling all the other
- windows! -- the previously active window becomes activated again and
- everything is ok.
