Exception Disappears When Thrown From DropDrop Event In A UserCont

[Jon]

I have a reproducible problem. In my application I have handlers for both
the AppDomain.CurrentDomain.UnhandledException event and the
Applciation.ThreadException events. Up until now these seemed to be catching
all of the unhandled errors in my application. However, it appears that if
an exception is thrown in certain UserControl subs that handle events that
the exception disappears and the application continues as if an exception had
not been thrown.

To reproduce this:
-Create a new windows form project and add a module with a sub main
-Use Application.Run from a Sub Main to start an application's form. Before
the application.Run line addhandlers for the
AppDomain.CurrentDomain.UnhandledException event and the
Application.ThreadException events.
-Add a usercontrol to the project that accepts drag events
-In the user control's dragdrop sub, throw an exception
-Run the app and drag anything on to the user control. The exception gets
thrown, but nothing happens.

What's going on here? Is there another way of catching unhandled exceptions
that would solve this problem? It seems as if the exception isn't being
treated as an unhandled exception at all actually though, because I get no
error window saying there was an unhandled exception.

Thanks for taking time to check this out,
Jon
