Modal dialog with two gtk_main() [Last try..]

[Sven Anders <anderss fmi uni-passau de>]

Hello !

Sorry for asking again, but I did not get it right...

What's wrong with the attached program? It's a much simpler version
of my problem, but why does it not work?

The first press on one of the main buttons works. But after closing
the modal dialog, the press on the other main button does not
work any more...

Please help. What's wrong?

Thanks in advance
and best regards
 Sven
