This is a patch file for "mathtables" 0.3.5. This file fixes a problem
with the program's About screen.

Details:  If the release in  question is  used with  newer versions of
"gtk", the Close button on the About screen doesn't work.  The problem
occurs because the About screen uses "pygtk's" version of a "gtk" dia-
log named  GtkAboutDialog,  and the characteristics of  GtkAboutDialog
have changed.  Specifically,  GtkAboutDialog expects the programmer to
process close-button events explicitly,  and the old About-screen code
doesn't  take this  into account.  The following  changes  correct the
problem.
