Trouble shoot javascript

We've got a website [login to view URL] - which is currently using a 'nivo slider' we want to change it to use a slider called 'jb gallery 3.0'. We've changed it over to run the jbgallery slider here - [login to view URL] - but a couple of errors have come up. The new site seems to work fine in FF, but not in chrome, safari, opera (havnt tried IE, but we will need it to work in IE too.) There also seems to be a error where the slide out panel opens and the closes straight away. I also want to use a loading gif while the the slider images are loading, but because the slider fades to white in between each frame you can still see it spinning, which i dont want, i only want to see it when i first load the page. If possible and if its not to much work, i would like the images to fade into one another rather than fading to white each time. The fix must be semantic, and valid js / jquery. Ill send over all the site files to the winning bidder. If you've any questions about the project just ask...
