threading issue

[Rick]

I have a form A that is running on thread A.
I have a timer that fires on thread B and tries to open form A.
Using .Net 2.0 it will throw a cross thread operation not valid error.
If I first test form A to see if A.InvokeRequired, it always returns
false.
If I suppress the cross thread errors, it will open the form, but hang.

Any suggestions?
Thanks,
Rick
