Thanks Greg. I'm making some changes today in an effort to clean up the
code and dispose of forms as I use them (currently I'm hiding each form
and instantiating new forms for each client), which I hope will help.
I've searched support.ms.com for system.windows.forms.dll but haven't
really found much, other than a hotfix related to datagrids.

I'll keep looking at update as I know more.
