[MonoDevelop] Cannot see form designer in MonoDevelop/Ubuntu 12.10

[mikey at lawtechgold.com]

I'm running Ubuntu 12.10 Quantal Quetzal, and installed MonoDevelop from
Synaptic, also gtk-sharp2.

Synaptic installed MonoDevelop 3.0.3.2.

Everything working fine in the IDE with one exception: When I create a
gtk# 2.0 project, I cannot see the form designer in the IDE. I can build
the project and run it and the winform launches, but in the designer I
can see only source code, not the GUI designer, when I open the
MainWindow unit, even though view is set to Visual Design. I must be
missing a package? 


What am I doing wrong? What am I missing that needs to be installed?
