“Undo” feature in Visual Studio 2008 stops working

Question

I\'ll be coding along in Visual Studio 2008, and eventually I make a mistake. I press CTRL - Z to undo and NOTHING HAPPENS. I\'m not talking about anything

Answer 1

I just had this problem of Undo becoming disabled. I'm using VS2008 Developer Edition. I don't have ReSharper intsalled. Going off @Joseph's suggestion I thought I'd check the clipboard, but before I did that I tried cycling the clipboard Edit -> Cycle Clipboard Ring and Undo came back. This is the first time it has happened. I will update this if it happens again.

Update Seems I got lucky. It happened again and the Edit->Cycle Clipboard Ring trick didn't work. This has never happened to me before, and the situation it is occurring in is novel too - I'm running two instances of VS2008 - one with a WCF service running, the other a simple web app calling the webservice. The really odd thing is, is that when I am actually debugging the undo icon becomes active! As soon as I stop debugging it greys out (in both instances)
