The error message you are seeing looks like a Winforms default one - can you trap the exception nearer teh site that it happens (maybe where you show the other form (if you call ShowDialog on it) so we can have a look at the exception trace and see what is generating the SecurityException

I see what you're saying Richard.
No COM objects... that's the weird thing about this whole mess. The failing
part of this app is just another form trying to load a grid with SQL data.
All built in .NET, part of the same project.

Partially trusted code doesn't get this permission by default and so you would get a SecurityException.
