I am fine with banner ads on the top and bottom of the pages. I know the bills need to be paid. But today I am having issues where after posting a message or refreshing a page, I get a single banner ad on a blank page. No other menus or toolbars are left. I can't even go back. I just have to close and re-open the site. This has happened 4-5x today, but it happens unpredictably. Am I the only one? Is there an issue with the Ad provider?
