There is a conflict with the ShareThis script and another script I have on my site. I've set up a test example here: http://jbrlsr.com/help.html to reproduce the issue, use FireFox and mouseover a few of the links, you'll notice "Transferring Data From" in the status bar area. To clear that message click on the ShareThis icon. There is one post I've found on the ShareThis Forums: forums.sharethis.com/topic.php?id=2415#post-4199 but no resolution. If you can pinpoint the issue and suggest a realistic/workable resolution I will PayPal you $100.
