Odd runtime error

I am gettin an error that I can not workout why it is happening. It seems to
happen when I select an item in my combo. Setting a break point, and
stepping through, or using try catch doesn't seem to trap it either.

From what I can see(and I look blindly) its some sort of unsafe method.

Any ideas ?

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

You wouldn't happen to be updating this component from a background
thread would you?

I have seen this error when using the call to
Application.EnableVisualStyles followed by a Application.DoEvents.

If you have this call too many times, I think it can error out
