[gtkada] Version 1.3.12 of GTKAda for Windows

[Chris Sparks]

Thank you Emmanuel.  This does help clear up the problem.  I just modified my
version of the GTK software to handle the null event and return "Nothing".  Thank
you for adding the comment.

I am not sure at what time I get this to happen.  Since I am only using GDK it is
hard to explain what I am doing.

Thanks,
