Thanks! That was what I was looking for, a reason as to why these classes were acting different.

Not true, although 90% of the things in the toolbox will be controls there are other things in there by default that aren't such as Timer. The original power pack shapes show up in there as well. I also have communication controllers that show up in the toolbox so I can drop them onto the form.

The project is included in the solution. And its not actually a control. the full object model hierarchy is
Myshape
Microsoft.VisualBasic.PowerPacks.OvalShape
Microsoft.VisualBasic.PowerPacks.SimpleShape
Microsoft.VisualBasic.PowerPacks.Shape
System.ComponentModel.Component
System.MarshalByRefObject
object

OK played around with that. If I force select it that way it pulls in the base class OvalShape not my AdvancedOvalShape. With my empty test class it does the same thing. However if I inherit from SimpleShape which OvalShape inherits from then my test class comes in correctly.
