I have been unable to comment on youtube from three different browsers and two different accounts... no clue why, the comment button will change twice in text and then nothing... It's been like that for awhile (few days), so I was wondering whether it was just me or whether somebody else is experiencing the same thing?

Try posting a url on youtube, it doesn't give an error and its impossible to copy your comment, yet it doesn't work (or it might actually be the slash sign). Whatever it is, I am totally sick of it. (Just thought I would partially explain the situation and wondered why youtube isn't showing an error)

Haven't tried to post a comment, but for the last few days if I move the slider to a different "time", I must click "pause" then click "play" before it will resume playing.

YouTube prevents it for spam reason. I'm not sure if it makes a huge difference. Yes, it's quite annoying, but their commenting system has never been great. It somehow just encourages people to say stupid things

Roger, perhaps you accidentally miss the slider at first and click on the video frame (which pauses it)? Maybe not, but i've been noticing that as well lately. I figured i was just pausing it accidentally
