Layout not updated by watch dog

I am using windows client 1.7.9 and i don’t know the cms version.The problem is its not updating the content require to close the window and restarting watchdog.

I can’t understand what is the problem is ??? whether it is a version problem or watchdog problem or else??? can you help me???

It sounds to me like you’re using very long durations on one or more of your media items.

Start out by reading the following:

Then ensure you are allowing time for the Player to collect from the CMS, and for your currently running layout to expire, before you manually restart the Player.

Got it Alex. I have changed collection interval , then problem has been solved.Thanx.
