Added a minimal example app to this issue.

OK I have the fix - I tested the example app on Windows with the following:

• pyjd
• IE 9
• FF 4
• Safari
• Opera
• Chrome

and all seems fine. There were two problems:

1. The DialogBox.py file was incorrectly using 'self' as the widget to trap events through GlassWidget. Actually, the mouse handler of the DialogBox is the caption and that is the widget to be passed. Also, since MouseHandler does not define the glass events, python exceptions would occur under pyjd, so the glass enter/leave placeholder methods were added to Mousehandler.
2. The previewEvent method in PopupPanel.py was relying on DOM to tell it whether a mouse capture was in progress. The GlassWidget IE override did not involve DOM in the capture/release. That has been fixed by allowing browser-specific implementations to set/release capture, then letting GlassWidget simply use DOM to set/release capture.
