Hello all,
I hope this is the right forum for this question, but I think so
as it concerns the AULab app. :-)

I have an AU plug-in which also exist as a VST plug-in for both Mac and
Windows. The plug-in has a rather complex GUI, and it makes AULab and
GarageBand a little bit confused. (Ableton Live & Apple Logic are not
confused.) I suspect that AULab and GarageBand probably share some code, or
possible the development team ;-)  ? If someone from there could jump into
this discussion it would be great.

Our AU plug-in is regularly opening child windows in terms of options,
popups, messages, tweak guis etc... These are all top level windows. Opening
these, using them, and closing the windows is no problem - the problem is
that as soon as one child top-level window HAS been opened from the plug-in,
AULab/GarageBand refuse to close its window containing the GUI. Very odd.
The little red top-left "close" button does not lit red when you hover over
it with the mouse, indicating that it won't respond when pressing it.
Pressing the "close" button of the window does not close the plug-in editor
GUI.

To sum it up: Opening a secondary free-floating window from the AU GUI,
inhibits the AU host to close the plug-in gui properly.

As a clue to the mystery, I can reveal that it is irrelevant if the child
belongs to the AU GUI or not, it could just as well be a window with no
parent.

Any ideas? Has anyone stumbled upon this too?
Thank you for reading this far.
