Working with COM control - "COM object that has been separated from its underlying RCW can not be used"

I have a COM control I converted into a user control hosted on a WindowsForm.  It was working great until I began an asynchronous version of the Form hosting the COM control.  The exception is "working with COM control - "COM object that has been separated from its underlying RCW can not be used"

Any ideas?

Did you apply all .NET service packs?

I remember having this issue a while back and there was a patch available. It seems to be included in the latest rollup patch too by now.

Tom -

thanks for the link.  I'm moving on to a different approach rather than jumping into this any deeper.

Did applying a service pack help?

Anyway, thanks for the bag of points for a shoddy non-solution ;)
