Move menu items causing user to go bananas

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Every time I want to move a menu item (from one menu dropdown to to same menu adjacent dropdown) by Cut in Microsoft Visual Studio 2005 it immediately crashes on cut with error dialog 'an error occurred while processing this command Object reference not set to an instance of an object'
I remove the click event and the error still occurs. Have checked other item references, and they are non manual entries.
Any advice? Thanks, Alistair.
