Site going screwy for me

Besides having to continually relog in, Lately I have beemn getting an annoying popup in the lower righr corner, that manages to elude my popup blocker. If I X it, it expands to a latge black block that takes up a half of a page. I have to get to the index and go to a new window.
 Also, the page starts scrolling to the right... to infinity, I guess.
 This happens when I try to post a reply mostly.  Not doing it right now !
Not happening anywhere else but this forum:14:

Clay I will see if any settings have been changed. I was having trouble at another forum and it turned out to be IE 10. I had not updated to IE10 Microsoft did it for me in an automatic update. I switched over to Firefox and now everything works awesome. I was also having problems at POGO doing the crossword puzzle all of those problems are gone now also. And when this was going on Other model forums I go to I had no problems with any except mad Modeler. Just to let you know.

I think you nailed it Buck. I was having severe problems on another site after the last IE10 update but since I switched to Google Chrome I've had no bother at all. AND it's much faster too!

Clay, many site problems are caused by external site issues.

I'm using Windows 7 with IE10 and have no problems. Set your compatibility view on and see if that helps, that's where I keep mine.
