Hi Chris!
I do not know enough Flash to even try to address your problem above or why it is occuring. I am trying to understand and learn 3 programming languages - PHP - JAVA - Flash. I have a pretty good understanding of HTML. However folks (not just Moodle) are going towards XML so I am trying to also learn this in small steps as well.
Right now I am trying to work on developing a WhiteBoard for Moodle with chat, audio, webcam and file transfer capability. I found an open source JAVA based program which could do this but Martin indicated he like a Flash based program better.
Mark Burnet has embedded Drawboard into a link on his Moodle site. You can find DrawBoard here.
A problem I see with JAVA and this new Macromedia Communications Server is the additional cost a webmaster may have to pay to have either one on a server so they can use the feature. I think the website must me located on a server running JAVA to run the JAVA based WhiteBoard. I do not know if the website must be on a Communication Server or if it can be on a separate one to run the Flash based WhiteBoard.
A poblem that I am having is I cannot get clear instructions as to how to install JAVA files to check out a program when using easyPHP v1-7. I have both of the following installed along with easyPHP,
Java 2 Runtime Environment, SE v1.4.2_03
Java 2 SDK, SE v1.4.2_03
If you are working with a MX Communications Server and you have the time I suggest you look at,
