I was prancing about in M&L inside story when I get into a Bowser fight against the large block dog. The screens split in half and replace each other, I wing it for a bit and then the emulator crashes.
The next time I attempt to play something, in this case scribblenauts, nothing I click on produces any results. I try this in M&L and the only place my cursor effects is the very top left corner of the screen.
I've searched through the forums and only found one post of this specific problem and it was alleviated by reinstalling logitch mouse drivers, which did NOT work for me.
