The show yar history feature stopped working for me, not sure how long ago (been out of town for about a month). It's not working for me with my usual browser which is IE9. I just fired up chrome to check that and it works in chrome Version 41.0.2272.118 m.
Just realized another related problem. Quote boxes in posts wouldn't expand to show the rest of text when clicking on the 'more' link with EI9 browser. This is the same if logged in or not.
Well, today the more link in the quote boxes is working but not the yar history link (my normal IE9 browser - I really don't like to fire up chrome to just look at one thing). Don't know if someone had done some work on things or my computer is messing with me. *scratches head*
