On the main forum display when I click on a forum to look at it I get the pop-up that gives the forum description just like if you hover of the forum. If you do not move the mouse when you click and the forum opens (XenForo Bug Reports for example) when you back out of the forum the pop-up description is still there. I can have the pop-up all of the forums if I want. If I re-hover over the forum the pop-up will then disappear. I can't duplicate it with IE8 but can do it consistently with Firefox on 3 different computers. I'm using FF 3.68.
