Description of Problem:

Application stop responding after calling Hide() method from Thread

Program (see attachement) should display icon in system tray, and show form
after choosing "Show Form" in context menu.
Method myForm.Run work in another thread. Method runs simple loop which should
hide myForm every 10 seconds.

Hide() works fine if it invokes from myForm.OnClick, but after calling Hide()
from the Thread (myForm.Run()) application stop responding to anything and
process "mono" start using about 99% CPU

Steps to reproduce the problem:
1. Sample code in attachement, build is and run
2. Dots will appear in console every secong - it means that thread (myForm.Run)
is running
3. Left Click on icon in SystemTray
4. Choose "Show Form"
5. Wait a bit
6. Dots will stop to appear
7. That's it.


Actual Results:
application stop responding to anything and process "mono" start using about
99% CPU


Expected Results:
myForm should become invisible, as it have been before clicking "ShowForm"

How often does this happen? 
every time

Additional Information:
I use Linux Fedora 9, think it should be similar to RedHat
