Who's chatting block does not update in real time

Hi,

Provided you have remote authentication enabled, the Who's Chatting list should be updated whenever a user logs in; however only new users logging in are updated.

Additionally, the who's chatting content is refreshed periodically through Drupal's cron hook; the timing of which may or may not be adequate for all of our customer's needs; especially if configured using Drupal's recommendations (only once per hour!). For the time being, please ensure that you have enabled cron jobs within Drupal. See: http://drupal.org/cron

We understand this system requires more attention, and should be fine tuned to ensure that Who's Chatting list refreshes occur once every 1-5 minutes.

A real-time refresh is, unfortunately, not currently feasible. As each Who's Chatting refresh requires a call to the AddonChat servers, a busy site could quite easily cause severe load on remote servers as the content would be loaded from each user accessing your Drupal CMS.

While we're awaiting to see if any changes will be made in Drupal 7's CRON/Scheduled Tasks system, we are considering discontinuing use of the Drupal cron hook in favor of built-in system to more smartly (and regularly) update the Who's Chatting list.

Users have been around for two days in the block "who's in chat". It is no longer in the chat nevertheless registered the block is full. Cron runs and still be in the user block. what can be? Version 6.x-1.5

I could now delete from the table addonchat_wc, but as the table automatically deletes itself?
