+ 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.
