Okay, question number two: what are your privacy settings on IE 6? To find out, go to "Tools" -> "Internet Options" - > "Privacy". If your are set to "High," move them down to "medium high." I have installed and configured portions of TILT and am able to run them with IE 6.0.28 with my setting on Medium High without incident. If I change my settings to "high," TILT does not work.
If this does not work, another follow-up technical question that you may or may not be able to answer: is the server on which you host your TILT files the same as the one users are accessing publicly? That is, it is possible to place your php files on one server and call to them from a webserver on a different box, apparently. IE 6.0 blocks "third party" cookies that do not have a P3P policy reference. The problem is, IE has difficulty determining who is a "third party" sometimes, I've read, especially where you are serving pages This all stems from a new web policy initiative called "Platform for Privacy Preferences," which has been established by the W3C: "The Platform for Privacy Preferences Project (P3P), developed by the World Wide Web Consortium, is emerging as an industry standard providing a simple, automated way for users to gain more control over the use of personal information on Web sites they visit." IE 6 apparently has some nice features that allow you to set up preferences that will check P3P policies and automatically either reject or allow cookies based on these user preferences. Pretty neat, but in the case above second party cookies will look like third. Regards, -Chad
