Please note that I am no longer actively developing this application as I currently do not have the time. The practice I work for has finnaly made the decision to get PACS so I am up to my ears in project plans etc.
If anyone wants to get involved in the project the source code for both the flex and PHP side of the application is avialable on sourceforge. I would be happy to assist with any questions if any other developers want to continue with the project for now.
