Another odd one which I suspect is me. I clicked on a variable and did Ctrl+R, R which is meant to rename a variable. When I try it, a message appears at the bottom of VS2010's IDE saying "The key combination (Ctrl+R, Ctrl+R) is bound to command (Rename...) which is not currently available." but that's exactly what I'm trying to do! RS's gutter appears on the right-hand side and it has the warning icon and some yellow bars so I think everything should be working as normal. Any ideas about this odd problem?
