Might want to double check the setting It could be hosed up and needs to be re-saved.
Control Panel » Display Options[-] Who's Online
Who's Online Timeframe:
Users will be listed as online if they have visited within this timeframe (in minutes).

I have mine set to 10 minutes I think that is the default.
