[Mono-winforms-list] MessageBox

[Ravindra Kumar]

Hey guys,
There is some unfinished code in Form and X11 driver that
is causing this. We are working on it. The problem will get
solved once we are finished with the relevant changes.

Sorry for the inconvenience.

Hi,
I just did a quick test and it appeared that this is not a MessageBox
problem. The problem certainly is in Form because any Form you try to
ShowDialog will just throw the same exception... A test is attached.
