Hello, new here, my apologies if this is answered somewhere else, I've looked and haven't found the solution yet.

I'm running Windows Ultimate on a quad-core Dell, so the capacity for animated desktops/dreams is innate to my system.  I've been enjoying using some of the great dreams which have been offered on this site.  Most run with no problem and look awesome.  Every now and then I try one which seems "broken" in that all that displays is a static image with no motion/variation.  From the comments on the demo pages, it seems as if these work fine for other, I've deleted and re-downloaded to see if the problem was a download error, but the problem seems consistent. 

In particular I've found that "DragonFlight 3" and "FutureWorld" show this problem.  Do some dreams count on having particular Stardock software installed for them to run? or is my Vista Ultimate just more neurotic than most?

Thanks,

Matt
