If I move the mouse into the empty space in the page, it shows me ads. That's ok. The problem is that it also shows me ads when I move the mouse into a Flash applet (I guess the program fails to detect that as content).
Ah I see. Can you tell me what OS & browser you were using? I've tested with many setups and the ads should go away when the mouse is over flash elements.
Opera + Flash 9 in Linux. I've tried in Firefox + Flash 7 in Linux too and it's somewhat messy there too. In both setups the ads appear and disappear at strange times when I move the mouse, not just when I enter the Flash area.
