I'm not sure how this happens, or why it happens, but on ALL XenForo forums, I cannot see any tooltips. Even here at XenForo.com, the tooltips do not work, instead it just shows the title text. This happens even if I reinstall Windows, but sometimes it does work briefly, so I'm unsure as to what is actually causing it. It only seems to happens in Firefox and Chrome, Internet Explorer shows them properly. I've attempted to remove Chrome and Firefox entirely and then reinstall, but it still doesn't help. From my testing, it seems to work fine on other computers on my network on all browsers, and I haven't had any other complaints, so that leads me to believe it's something unique on my computer that is causing it, but I don't see why it'd target XenForo. I haven't noticed any other sites performing oddly, and I don't have anything that would be blocking any resources. See attached images to see what I am talking about.
