I'm hosting a conference and my guests tell me that my screen refresh is too slow

These are most common causes for poor performance, frequent disconnects or screen freezes and their respective fixes:

• You have very little "Download" or "Upload" bandwidth.

• There is spyware installed on your computer.
  (Learn how to detect and fix this problem)
• Your Desktop Wallpaper (background picture) is too detailed.  Please remove it to increase performance.
• Your bandwidth is too limited to send your screen at 32-bit or 24-bit colors.  Lower it to 16-bit by Right-clicking on your desktop, select Properties, choose Settings, and set the colors to 16-bit.
• A program is interfering with your Internet connection. Try shutting down any programs which may connect to the Internet. (e.g. Windows Update, Norton Antivirus, ZoneAlarm)
• Your computer has run out of resources:
  Try rebooting the computer. This will free up memory and network ports on your computer.  Only load the programs you need for your conference.
