This morning I noticed I can't open the comments panel under a video when I simply click on it. I can however, open it in a new tab. It does seem to fully function in that new tab, but I'm sure that's not as intended.
Browser: Google Chrome
OS: Ubuntu 12.10
EDIT: Appearantly it shouldn't appear when I click on it, as the comments section should be there by default. Swapping between the video tab and the comments tab didn't do anything. Also I should note that I thought this wasn't posted, since I got an Error 500 when clicking submit. Checking the forums later on a different PC (Windows 7, Chrome) made me realise it did get posted after all.
