to be seeing this problem.
Of course, it would help if we knew what version of the OS you are running,
what you were doing just prior to the problem,
If you had installed anything recently,
Peer to Peer downloads, Limewire, etc.?
I can make a small cartoon of a mushroom cloud appear, make a sound and dissipate. The system does that when you drag an icon off the dock and onto the desktop.
Have you run Disk Utilities yet?
What happens if you create another account and log into that? Same thing?

Yesterday something took over the desktop of my eMac. The desktop is framed by a transparent gray frame that pulsates in and out. If you open a window, the window begins to jump on and off the desktop, taunting you. At one point a small cartoon of a mushroom cloud came on the screen and made a sound and dissipated. Then a picture of someone's face came up. I think this is a very serious problem. Although I have no idea how to address this, why isn't anyone talking about it? Am I the first person on Earth to see this thing? Help!
