So I just applied the latest patch, went to open the game... and my cursor is lagging like you wouldn't believe, until I exit back out. I'm running Win 7, using an iHome wired mouse. Anyone else seen this or a similar problem, and have any solutions? (I haven't changed the game resolution, or done anything other than the new install.)

Update: so apparently, this is only happening on the main menu screen. Once I get to the game itself, everything is fine. Which means that I can just use the keyboard to start (and save) the game, if I have to. But it's still an annoyance, and I'd like to know if there's a fix for it.
