Egad, just when you thought it was ready...you get this: "Error: uncaught exception: Permission denied to call method XMLHttpRequest.open" This is in FireFox 1.5. It worked perfectly at work in FF, but I come home and begin to implement it, and now it fails in FF at home. The script is in the same domain, so I don't get why this would happen...any ideas on how to debug this? Now it works just fine in IE - I'm getting too old for this!
