Mobile WebBrowser control causes my application to exit

I have a Windows Mobile Standard application written in C#. In the application is a form that displays a record, originally drawn directly to the form in the Paint event. I recently replaced that to used a WebBrowser control ins开发者_如何学Ctead to make it easier to render complex text formatting. However, when the form closes (opened using ShowDialog()) the execution path continues all the way back to my Application.Run call and the application exits. If I remove the WebBrowser, the form closes okay and returns to the main form as expected. When I put it back in, the application exits again.

The data is passed via an object parameter in the constructor, then the WebBrowser is populated in the Load event. I've removed events from the control (it uses the DocumentCompleted and Navigating events) and it still exits.

I used the WebBrowser control in a previous application with no problem. I'm not sure where else to look and hoping for a point in the right direction.

Update: This problem doesn't exist on a physical device, only the emulator. A bug in the WebBrowser or emulator libraries perhaps?
