From Perl/Tkx why does the call

cause the toplevel main window to blink (disappear and re-appear

I am trying to disable toplevel window resizing but I would rather
not have the app blink.
Is there something extra I need to do, or a different command, to
accomplish the same thing without making the main window blink?
There are a few mantras to hold by in building a Tk app. Toplevels by
default display at the next update event, whether they are ready or
not. You should always start building a toplevel by doing wm withdraw
on it, then build the UI, make the other wm attribute changes (like wm
resizable and wm geometry) and then wm deiconify it. Sometime wm
geometry wants an update idletasks (full update not necessary)
beforehand.
