Multiple calls to gnome_app_new allowed in single app?

[Natasha Westland <westland ll mit edu>]

 Hello,

Is it permissible to make multiple calls to gnome_app_new() within a 
single application?  I have an app which creates the main window using 
gnome_app_new() and then as a result of a pull down menu option, creates 
another window using gnome_app_new() as well.  The second window has a 
vbox as well as 4 buttons on the bottom.  The problem that I am having 
is that sporadically, all the widgets in the second window become 
non-responsive and the only recovery I have is to restart the entire 
application. I have tried adding hooks which will kill the second 
window, once it becomes non-responsive, and will then recreate the 
window (using gnome_app_new()) but the new window remains non-responsive.

Is it possible that subsequent calls to gnome_app_new are stomping on 
some globals somewhere in the GDK library?

version info:
OS: CentOS rel5.6 32 bit
Gnome 2.16
gdk+: 2.10.4

Thanks for any pointers.
