movie question

I have a image control with
<animation effect slide start 0,-200 end 0,950 time 30000 delay 5000 loop true condition=true. Conditional</animation>

The thing is I want it restart if I change windows. This animation is on the home menu. And will not restart… If I use window open as the condition the it does not loop also when leaving the images gather in the top left side…

And advice will be helpful.
