Tkinter: closing app with active messagebox

[marten at btk.utu.fi]

Hi

Im writing a small script that asks the user for some input and checks
it from a mysql server. If the user doesn't respond the app should
close after a  timeout period. Normally this works fine, but if there
is an active messagebox (tkMessageBox.showinfo), the app won't close
until the OK button in the messagebox is clicked.

My question is: How do I force an active messagebox to close? Can this
be done with the standard dialog boxes in tkMessageBox or do I have to
write my own dialog boxes?

Any help appreciated

Yours
