Agreed. As Pauli might say, physics without math is "not even wrong."

I have this problem too on Hulu and Youtube alike. I found that if I click and hold the middle button on my mouse and click the first button, I can use the controls again. Pretty ugly hack, I know, but it works! What's worse is that this bug comes and goes, and I can't figure out what's causing it. In fullscreen mode, the controls work normally again.

Linux is pretty much a herd of cats developing software. There's no way you could get a Grand Unified Linux.

Along with the other comments here, I would also like to point out that arXiv is _not_ peer reviewed. It's really frustrating the amount of citations from arXiv I've seen lately. People need to take everything from arXiv with a grain of salt. Sure, arXiv is there to spark discussion, but until it ends up in a peer reviewed journal, treat it as hearsay.
