Flash/PHP/XML problem.

We have a main flash/php program that calls up other flash games from links inside it. It is working absolutely fine when the user is running IE6, but when IE7 is being used there are problems and the links don't connect properly. All these files are installed onto the user's computer. Basically, the user logs into the main flash program and then chooses what game to play from the links. It's just that IE7 is presenting a bit of a problem. The other part of this job is that we would like a "noticeboard" square on the main screen that will call up some HTML from a file on the server so that we can show the latest offers we have on the user's screen, instead of changing the swf file all the time. We think it is some XML thing, but we don't know how to do it. This is a really urgent job, so we'd like it done asap, and we don't mind ending the project early if we have a good bid. The winning bidder will need to sign and return a Non Disclosure Agreement. The budget is set to 30-100, but if more work is needed, we can go a bit higher.
