js. conflicts on all sites I install this on

Hi all - I've installed this plugin on 6 sites in the last 3 days and it has had to be turned off on all of them because it causes js conflicts with multiple plugins. Any ideas? I've also notice that it creates "on page" scripting which I'm not too fond of - again, any ideas? If someone is interested in seeing the problem in action let me know and I'll enable the plugin on a site.
Thanks!
