is anybody familiar with greyBox JavaScript plugin?

it's for slideshows and stuff.. I can't get it to work in FF/Safari; it works great in IE, but FF/Safari won't play ball..

would very much appreciate some suggestions..
supposedly there's a google group (forum) for this thing (, but when you link to it you land on a pg that says they've been booted out b/c they violated google's terms of service....;-)

thank you..
