This morning, every time I've voted for an answer, I've gotten a popup telling I haven't voted for a question recently. Since that's an extra click to dismiss, and since I haven't seen a question worth voting up recently, my first reaction is to stop voting on answers rather than go on an extensive hunt for questions worth voting up.
Please make this popup less obtrusive. Either make it fade away quickly on its own without being clicked on, or make it only show up every n'th answer vote.
Update: Ok, it does fade away on its own, just slower than I expected.
