I just had a first time ever error message in IE. The top US Air add loaded and I was waiting for the rest of the page to load. I hit refresh and no luck. I then tried to exit and a warning box with close or cancel poped up... it said,

"Warning, the window is trying to communicate with a.tribalfusion.com and closing the window may cause damage to your cookies."

I guess this is a new warning window in XPII as I have never seen or heard of anything like this. I did exit the window. It looks like we are back to tribalfusion problems and an add gone bad.... just my guess.
