Do the Window shuffle...

[GRE Spam Mail <gre_spam anora org>]

I'd like to know how (1) I can make a window be "always on top" and 
(2) temporarily disallow the user from changing to another window in the same
application while this "always on top" window is active.

I looked through the archives, but I didn't see anything covering this.

Thank You,

Gordon R. Ellsworth, Jr.
