hi guys ,

Have you tried using Rev slider just to find out that it works when the browser window is focus.

However , when you click on a new tab and go back to the page it stops working.

Not to worry about that anymore after surfing the net I was able to see some quick answers.

Here is what you do.

Go to the General Settings > Misc > Disable blur / focus behaviour set to ‘on’

and you will be fine.
