Tk system modal window

[Elliott, Don (Police)]

Hi all,

I have a perl Tk program that displays a prompt line in a window.
Does anyone know how to make this line always float to the top.
 i.e. no other window should be allowed to be displayed over top of it.
 I am running on windows 2000 with activestate perl build 623

I think this mode is called system modal, but that is just a guess.
