Automatic log out
After thirty minutes of inactivity the system will automatically log you out, this is a standard security feature web browsers have in place.
One way to avoid this any where that you are entering a volume of text in a webform is to use Ctrl-A, Ctrl-C to copy all the text before clicking on the submit button in case the connection drops. This then saves the information and can be pasted back in if needed.
