Using IE 5.5, periodically when patrons are using Yahoo or Hotmail they will receive a message that they have been logged out. There seems to be no overt action that cause this timing out, and the length of time logged on seems irrelevant. Needless to say, patrons, who type in an email just to get a message that they are logged out when they try to send, are restless. This problem arises a small percentage of the time. I have wiped out the Cookie folder's contents and the problem again returned. Any ideas?
