I've come across a very annoying pop-up these past few weeks, and it only shows up when I visit Planet Gamecube. It's a small pop up that asks "Do you want to Run IE Browser Enhancer?". I click Cancel but it just pops right back up and won't let me shuffle it to the background or operate any browser windows, and usually results in me having to go to the CTRL+ALT+DEL window and shut down ALL my browsers. It's really getting annoying, especially when I'm in the middle of an article. I'm pretty sure it's not my ISP because this is the only website it pops up on.
