           Summary: Calling Dispose() on a child window kills the entire

Visual Studio 2005 solution

Description of Problem:

The attached testcase contains a form (the "primary form") that opens a second
form (the "child form"). The child form has a single button. When this button
is clicked, the click event handler calls Dispose() to close the form
(traditionally, you would call Close()). Rather than only closing the child
form, the call to Dispose() apparently kills the entire app...both the primary
and child forms disappear. There is no apparent exception being thrown, or
signal being raised, so I don't know exactly what is happening. Maybe the call
to Dispose() is disposing of the primary form too?

Steps to reproduce the problem:
1. Unpack the attached archive, which is a VS2005 project.
2. Build it, run it in Mono 2.6.4.
3. Click the button on the application's main window (a second window appears).
4. Click the button on this second window.
5. Watch as both windows disappear.

Actual Results:


Expected Results:
With Microsoft .Net 2.0, calling Dispose() on the child window only makes the
child window go away. The primary window stays up.

How often does this happen? 
Every time.

Additional Information:
Running CentOS4.3 on a VMWare Server virtual machine.
