chuleto1 has asked for the wisdom of the Perl Monks concerning the following question:

Once again I find myself asking for wisdom

I have a Tk window that at the click of a button will spawn a pop-up window. Is there a way to force the user to interact with the pop-up before going back to the parent window? I want to avoid the user going back to the parent window and spawing multiple pop-up windows before dispatching previous ones.
 Thank you
