#!perl -w

use Mac::Menus;

$old = GetMenuBar();
ClearMenuBar() 	;
print $a=<STDIN>;
SetMenuBar($old);  #Don't forget this line or you will be in big drouble :-)

Runing this little script on my Mac (PPC, OS 8.0) can disable menues but
not the whole menu-bar:-(

[1] Starting the script, while the <STDIN/SDTOUT> console-window is closed
will put an menu bar with just an enabled Window menue on the screen.

[2] Starting the script with the <STDIN/SDTOUT> console-window still open,
will lead to an unpredictable outcome.
Mostly I get an menu bar which looks enabled but actually it is imposible to
pull them down. Sometimes I get an empty menu-bar.

Does other MacPerl user have the same results? (Some email reports would be nice)

Searching for MBAR-ids, trying to understand the MDEFs...., BUT I won't give up:-)
How much is Mercutio involved in this stuff? (Kind of talking to myself)
