Dang It.... IT Works Now.. in simplified form! :/ see code below.
Must be one of the Glade Containers i plop the GtkClutterEmbed contrin into.
:/Hmmmm......
Anyways... i guess i'm stuck debugging it more. :)

Subject: Mouse Movement in Stage
Date: Thu, 2 Jun 2011 23:30:09 -0400
Hi All...
Trying to Accomplish: - Draw a Selection rectangle, like on the desktop, but
in a GtkClutterEmbed stage.
Problem: - Top and Left allow for < 0 (values) for Mouse tracking, but bottom
and right seem to constrain the mouse to the Stage width/height.
Question: - Is it possible to remove the Mouse input tracking constraint from
the bottom and right sides?!?
An example can be provided if needed.
Thanks,Izzy.
