There is also a more descriptive version on the Nvidia Website. (But seriously, Want!)
It seems that under windows, CSS hovering/fixed DIVs/Classes take LESS priority than Youtube. When scrolling down this page you may notice a “< Older” bar following you down. This feature is part of K2 by default, it works fine under Linux and OS X but in Windows Youtube videos take priority and seem to sit on TOP of the hovering div whereas my embedded video goes UNDER the div like it should.

I am yet to figure out why this happens, If I can figure out whats going on I will try to fix it. (Z-Index Perhaps?) It seems to be fixable with the following perameter in your youtube embed.
<param name="wmode" value="opaque" />
Questionable Working-ness.
I needed a ToDo list so I made a really basic VB.net one. It will probably never be updated, nor fixed. But there it is. It should be virus free, I just scanned it with McAfee (ahh McAfee). It is avaliable under the BSD license, If you want sourcecode please feel free to contact me.
Known Issues:
If you haven’t already seen the new ads Microsoft have been running you are probably one of the lucky few. Personally I think there playing some spin on the mac ads.
How ’bout, I’m a PC and using Linux was my idea. K-Thx-Bai.
