The entire system seems very slow.
A1: Up to 10 people at a time can use the system. If there are that many people in at the same time then it is likely that it will be slow. We are monitoring usage and will increase capacity as demand increases.
A2: This system is partially dependent on the speed of your internet connection as well. Make sure that you have all other programs that might access the internet closed to make the most bandwidth available for screen redraws (i.e. programs like personal e-mail, internet pages, Peer2Peer file sharing programs, etc.).
