Streaming cam images no more--why?

[MageJubi]

Finished a fresh install of Vista business, and all seemed ok--until I looked at my two weather cam urls (they stream fine in XP). The image pops up, but without any streaming capabilities. Hitting "refresh" does not advance the time listed on the images either. The cams feed into a server, then back out to the net. On XP, they popped up and ran fine....here's the odd part--one of the cams is a Stardot Netcam--it'll run fine directly, but not through the server. I've checked about everything I can find, or think of, from "internet options", to shutting down the firewall, to reformatting, java settings, permissions, etc....nothing. If I "X" out of the url, and reopen the link, it'll be at the current time, but that's as far as it goes. This is the last item that needs attention on Vista--all my other programs, etc. work as expected. Thanks for any insight
