why moving to new Glade version made GUI lose widget? (toolbar)

[seberino spawar navy mil]

We moved a Glade file (using libglade too)
from the old version Glade on RedHat 9
to the new version of Glade on Fedora Core 2.

We noticed when we run the GUI it loses the toolbar
because of using newer Glade version.

Any ideas why??

Are there well known gotchas about losing widgets
when moving between Glade versions?
