Mark,

I'd agree on the bug of this. The debugger should hang stuff like this up.

>Even though this only happens when a form property that does not exist on the active form is being "watched" and can not be evaluated by the debugger, I am going to consider this a bug because of the following. I could have multiple forms open where I am trying to debug some problem where not all the forms have this "property" I am monitoring in the Watch window. It would be a PITA to have to remove this from the Watch window in order to properly close a form that does not have this property only to have to re-add it when I am on a form that has that property.
