There's that. I crashed by pressing the windows button.
I'm noticing this a lot with block placement too since updating to 1.9. Clicking when the crosshair is over the edge of a block closer to you while you're moving the mouse towards an adjacent block will usually put it on the other block instead of the one I wanted, which doesn't happen nearly as much in past versions.
