This is a problem that started just a couple of days ago. On certain kinds of objects, specifically flash cartoons/games, a border will appear around the item when I move my cursor over it. This isn't such a big deal, but it won't let you actually interact with the object (like clicking buttons) until you click on it once. Once it's clicked, the border goes away and everythign works fine until the next time you try it. This gets very annoying when trying to navigate a site that uses lots of these kinds of objects. If I hover over the object, it says, "Click to activate and use this control." It can't be right clicked until I "activate" it. This happened right after the computer needed to be shut down to install some updates, so I wouldn't be surprised if Microsoft is behind this (I believe my OS is Windows XP home edition).

Any suggestions on how to negate this thing? It's just so dang irritating.
