MDI Child Display Issue - Getting a "First chance exception"

We have created a Winforms application that using MDI. On certain machines,
we get a "first chance exception" whenever we open more than one child form
(different child forms- we only allow a single instance of any given forms,
but have 5 different child forms). Some machines do not have this problem
at all. On machines that get this exception, the child forms will have
serious painting issues, and will display multiple minimize/maximize toolbar
buttons in the container form. There seems to be no rhyme or reason as to
why this is happening- all machines are Dell's. Both newer and older
machines experience or don't experience the problem. There is no way to
trap the exception because it seems to be occuring outside of our code. (On
a side note, we've also seen it occur on a child form when we are adding an
item to a datagrid for the first time).

Has anyone else ever had this problem? A former co-worker said that this
came up and claimed it was a video driver issue. However, I can't imagine a
video driver issue would be that widespread... We have tried the latest
video drivers on machines experiencing the problem and still have the issue.
