We've discovered a problem in the quartz window manager in Apple X11.
I'd report this as a bug if somebody could point me to where they've hidden
the page to report bugs :-)
Here's the scenario...
An X client opens a window (call it A) with a child window (call it B) and
B has a modal child window (C). While the modal window is up, the user can
click the red close gadget on window B and it will happily close B, taking
C with it. It also appears that if window B is closed in this way, window
C
does not receive the event telling it that it's being closed, so it gets
stuck in
its modal loop waiting for the user to close a window that they can no
longer
see.
Other window managers in X11 disable the close gadget on any window which
has a modal descendant.
We once had a similar problem in our Windows X server product (MI/X) and I
had to add a check in the window manager to prevent it.
