We have been using Visual Studio 2005 for a while. We seem to keep having this problem with keys not working all of a sudden. The other day I came across this post that has the reason. Now I did not think anything about it until peterpr started to complain and said he wrote some macro to unbind / rebind all the keys. I looked at him and said binding had nothing to do with it, it was a focus problem. He immediately threw a pen at me and asked why I had not blogged it. Well here you go.
BTW : I have gotten into a bad habit of always calling people by their email alias’. It is common in Microsoft so everyone is now an alias.
