If I may ask... what system are you surfing the site on and what is the speed/type of the internet connection to it?

I don't think that there are any browser specific issues, but I'd recommend either FireFox or IE though. Also if you have a really old system on a weak bandwidth link then it will of course load slowly.

You could alternatively use the subSilver theme if that seems to help.

If you are having serious problems I'd recommend sending a message to savage about it. I am no longer maintaining the PGD scripts.
