I appear to be having this same issue, the weird thing is, It was working perfectly fine yesterday, no issues ran perfectly smoothly, but when I try it today it will not work. As far as I know when I shut down my machine yesterday there was no updates queued up and waiting to be installed so I will be ruling out that. The other weird thing is that i'm playing using Minecraft version 1.7.5...from what I see above it seems that other people are using a new version and having the same issue, so I think it is a long standing dormant bug that awakens at some points due to some system change or something. I don't know, I am far from a technical annalist.
