I just noticed this today. Links in the description to the right of the actual youtube video are not working.
Here is an example (not my vid btw)
. I can not click on the site featured beside the video, its just not showing up as a link, although its still in bluetext. (just noticed u will have to click through and watch the video on youtube to see what Im talking about)
I tried this on both my computers which are vista and using latest versions of IE. It works ok in Firefox though.
