I would strongly encourage you to install a fresh copy of MC to verify 
this issue.  While many of us saw this with earlier builds, I believe 
all of us have seen this addressed favorably in RC1.  This is consistent 
with the logic of what was happening:

Klaus' minimize code was in the "MetaCard Menu Bar" stack in previous 
builds, and as the mainstack for mctools.mc it was affecting all other 
stacks.  For RC1 I moved that to the card level, so that it still 
handles the minimize for the "MetaCard Menu Bar" stack as expected, but 
it no longer in the message path for anything else, such as the Message Box.

Klaus has confirmed that his original iconify code is no longer at the 
stack level in RC1, and Jacque has confirmed that her earlier report was 
mistakenly using B12, and that once she was using RC1 the anomalous 
behavior with the Message Box went away.

If you do find a repeatable recipe for this in RC1 please let me know.
