Ghost (flash?) advertisements on the desktop.

[Linuxguy123]

I get ghost images in applications on certain areas of my desktop after
I open a website with an advertisement.   

The advertisements appear to be flash based. 

After a while the ghosts disappear and aren't a problem any more in the
session.   When I start a new session I get a ghost and it hangs around
for a while and then disappears.  I am not sure what causes it to
disappear. 

I am running a fully up to date F14 installation.

I have not searched Bugzilla for information on this situation.  There
was an article on www.linuxhomepage.com that spoke of a similar issue,
but I cannot find it anymore. 

Any and all advice for handling this issue is appreciated.

Thanks.
