           Summary: System.ArgumentException: Cannot activate invisible or

          Priority: P5 - None
         Component: Windows.Forms

This exception was triggered when my app received a TCP/IP packet (sent by me
from client software). The entire stack trace spat out by mono is in MWF except
for the top. Program.cs line 23 is the  Application.Run(new MainForm());  line.
 I don't understand why there is no mention of what it was actually doing when
the exception occurred (the TCP/IP stuff). What other details can I provide? In
any case, why does an attempt to activate an invisible or disabled control
cause an exception? I'll be looking through the network code to find more
details. Thanks :)


Unhandled Exception: System.ArgumentException: Cannot activate invisible or
disabled control.
