More info:
It seems if I drop the same control on another form within the same project
it works BUT the form can't be a MdiChild form. If I try it on a child form
I get the same error as before.
This was working fine and just stopped working when the IDE got weird.
One more point worth mentioning: I left my computer running the other day
with the project open and running in debug mode. When I come back to it the
next day, the machine was locked up and I needed to hit reset. I don't kow
if this has anything to do with it.
