Why the Save dialogue in OS X

[Gregory Lypny]

Hello Jeane,

Thanks for responding.  If by "belt-and-suspenders" you mean 
unpredictable, then you're right.  It seems to happen to a couple of 
the stacks in my project but not all.  And for those couple of stacks, 
not all the time.  I've got other projects where this does not happen 
at all.  I'm not convinced that something is not amiss, perhaps some 
sort of message passing that I'm doing in some stacks and not others.

I'm a little concerned that this will create confusion and be an 
annoyance to my users when I build a stand alone.  Many different 
stacks are opened and closed as simple information windows.  The idea 
of saving makes no sense for these because there is nothing to save.  
And if there was, I thought that closeField and closeStack handlers 
could pretty much ensure that data won't be lost.

Regards,

	Greg
