O dear.  Thanks for enlighten me.  I wonder why that worked in previous
versions.

Yes it works.  Thank you very much.

Hmm, that's reasonable.  The actual displaying happens in
ApplyPicture().  Would it help, if I avoid gtk_window_show() in that
very case, if an configure_event was caused?  I'm not really sure
which call is in fact responsible for the displaying and I really
want to avoid that the image is displayed twice.

Thanks for your help
