Thanks for the responses guys - it is a military computer so I can not update anything - it is locked down for any user installs. My guess is that it is the latest version of IE, since the IT guys are rabid about security updates.
The bizarre thing is that it doesn't do it all the time. On one page all will be fine, then I open a forum and there go the graphics.
Ah well, I only volunteer there 3 hours a week so I think I can stand the hassle. At least I am no longer there 40 + hours a week!
Ain't retirement great ! ! ! ! !
