Locks - timeout

I'm a new MM user. This may have been covered before, but can someone explain to me about the way that locks are supposed to work. I was under the impression that after ten minutes the locks are released, allowing another user to aquire them. I'm sitting at work awaiting the locks for a page to be released on a co-worker (who has gone to a meeting) page to be released and it keeps going in a loop at about 8 mins 30secs - then goes back to 10 mins. Whats the point of locks then (apart from stopping 2 or more people overwriting each others content at the same time). If my co-worker does not come back/gets hit by a bus - will i need to pull the power out of the computer to acces the page i want? Is this the way its suppopsed to happen??
cheers

Hey Steve:


If your co-worker has left his browser open on that page, the locks will be kept indefinitely (Matrix will refresh them automatically). This is to ensure you don't lose the lock if you spend more than 10 minutes editing content, for example.



However, if you navigate away from the locked page, or close the browser without releasing the locks, they will timeout after 10 minutes.



A System Administrator can Acquire the Locks (i.e. force them to release). This will cause any unsaved changes to be lost, though. Also, in the latest versions of Matrix (v3.12 and higher) a system administrator could navigate to a user's detail's screen to release all the locks that user currently holds.

There is also an option to end user session if he/she has been inactive for some time.


System Configuration > Global Preference > User Preferences > Session Expiry Rules > When the time since their last Matrix-Activity is longer than x



(However, it can be annoying to lose your unsaved work when you come back to your workstation after a short break, due to expired session + auto logout.)

But if your locks are refreshing, it would still be considered Matrix activity, so the user would not get logged out.
