Hi,
I am not sure whether this is a bug of the cocoa widgetset, or whether this
is a general limitation of the Mac.
Imagine a main form, which shows a modal form. The modal form shows a
message dialog (ShowMessage or MessageDlg, it makes no difference).
This works perfectly on Linux and Windows.
If you do this on a Mac, then the program hangs: there is no way to press
the OK button in the message dialog.
Is this a limitation of the Mac ?
I have never seen a Mac program do this kind of thing, so I could imagine
that this is a limitation, but admittedly my experience on the Mac is not
as big as on PC...
I made a small sample program to demonstrate the issue:

If this is supposed to work, and it's actually a bug in the cocoa widgetset
I will post it to the bugtracker.
Michael.
