I have a problem with the IsOnline property. So far, whenever a user signed in, they would show up as online in the list of online users and the time window I set for online status in the web.config file is 10 minutes. When they log out or just stay inactive for more than that period, they would not be shown in the online users list. A strange thing happened yesterday. One user keeps being online for 2 days straight, and I do not beleive that is the case. I even log into that user's account, and log out myself, but after reloading the page that shows who is online, that user again shows up as being online? This only happens for this user, nobody else. Is there something wrong with this user's computer that keeps updating the LastActivityDate constantly? I even tried changing the LastActivityDate manually, but on reload, the user's LastActivityDate gets updated automatically. Why is this happening and how can I fix it?
