JavaScript greybox -- slidehow won't work in FF/Safari

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 (http://groups.google.com/group/greybox), 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…:wink:

thank you…
