Thank you Patio. Your information on Quicktime and SMC Fan Control is valuable for future reference.

Thank you Nya, I did indeed post it twice by error. And whatever was in the way under Viewer 2 has now been resolved by the Beta viewer.

Thank you, Belladonna. If I have further trouble, I will try Phoenix.

I am running OS 10.6.5 on an iMac 24 and the Beta Viewer looks like it is functioning properly.

Thank you for your replies. I installed the Beta Viewer and SL is functioning properly.

I recently upgraded to OS X Snow Leopard and downloaded the most recent version of Viewer 2. The login screen is fragmented and frozen, including the login boxes. The system requires a Force Quit to close it. I would be grateful for helpful advice.
