Issue #1 would be a side effect of the new animation the indicator does. It used to just blink over to its new position, now it will ignore input if the animation is running. I hadn't considered that as I don't play it particularly quickly, and will back the change out.
When a game crashes, you can press B to get a crash report. If you are able to get that to happen again, let me know what it says so I can track down the cause. I'll put up a patch release in a little bit that addresses the cursor movement.
