Smilely HELL bug in a recent update.
It appears once you start a smiley with a colon you get a popup with some text options, i.e. : smile : etc., but without the spaces. The issue is the pop up does not disappear. You can hit ESC to make it disappear, but once you start typing again it pops up and follows your text, sometimes covering what you are typing. This is VERY annoying. I only noticed this in the past few days on different browsers. I figure it must have been an update.
