A From won't close (c#)

[Yuriy Zubarev]

Hello everyone,

I have main application form (child of System.Windows.Forms.Form) that
hosts quite a number of different visual components. Some time after
working with those components, the form refuses to be closed - I click
menu item that invokes Form.Close() method, I click 'close' icon on
the caption of the window (form) - nothing happens. No event comes to
Form_Closing(Object, CancelEventArgs) method either.

I'm at a loss how to even start debugging this situation and I would
appreciate any suggestions.

Thank you for your time,
Yuriy ZUbarev

What's version of .NET? There was a bug in 1.0, but repaired in 1.1

I have 1.0. Was it a bug in Visual Studio or .NET Framework itself?
Any way to patch it?

Thank you,
Yuriy ZUbarev

Maybe the famous "form close bug"?

C# code to repro the close bug:
