Unhandled Exceptions - EXE vs. IDE

[Steve Blumenstein]

My app is MDI written in VB .NET. The parent opens a child form. The child gets an error in the load event handler which doesn't have an error handler. Executing in the IDE, the error is properly passed back to the error handler of the parent, a message is displayed and the child form is closed. However, when the app is built and executed from the desktop, the error is NOT passed back to the parent and a fatal error occurs saying that an unhandled exception has occurred in the app. The title bar of the error indicates that the error was issued by Microsoft .NET Framework.
Has anyone out there seen this one? Is it a bug in the framework? Any help will be greatly appreciated.

What exception? Maybe adding an error handler to
'Application.ThreadException' helps.
