Thanks very much for the response, especially since my question was  
rather newby. I realize that this problem is common to all platforms, from
Apple to Sun. I was just wondering whether asetroot (or something
else) had the facility to load wallpapers into memory.

I assume then that refresh speed is tied to the speed of the hard drive?
