Re: gtkextra-2: Problem adding children to inserted rows in a GtkSheet

	Hey folks:

	Anybody still on this list?  Adrian?  Just wondering if gtkextra has
been abandoned since I looked at it last (which would be a real shame),
or if it's just spring break...  

	I'm still trying to figure out a workaround/solution for the following
problem, if anybody has any thoughts.
