I can't read notes/translations on a picture. I have adblock off. Any ideas why?

Not sure, but when I just checked they didn't work for me either. If you right click and inspect element on where the box for the note is you can see the text for the translation on one of the elements right next to it though.

For the web developers in the house:
I checked the note objects, there are no events defined on them (besides the document events on everything), and forcing pseudo-classes didn't seem to cause any changes from css rules. It looks to me like someone accidentally removed the hover effects.

Are you using firefox? If so, switch to another browser, at least until this gets fixed (if it ever even does get fixed). I use internet explorer now to fulfil my hentai-related needs.

Similarly, no notes are visible for me when I browse with Maxthon, but they appear just fine when I use Tor.
