Test program for MenuStrip Bug

Description of Problem:
Typing ALT to activate the menu doesn't work (tested in Mono 2.0.1 on
Linux/Windows)
MenuStrip even crashes when ALT key is typed in a TextBox and then type arrow
key left or right.

Steps to reproduce the problem:
1. create a windows form with a menustrip (with two items) and a textbox (see
attachment)
2. Run program 
3. Click in the textbox and press the Alt Key twice!(on Linux it also crashes
when alt is only pressed once)
4. Press the right or left arrowkey


Actual Results:
mono crashes with an error:
Unhandled Exception: System.NullReferenceException: Object reference not set to
an instance of an object
