Switching screens cause apps to close and reset

[alleykatt]

How do I stop my apps from closing and reseting every time I switch screens?

Does anyone know why it keeps doing this? Is there a way I can stop it?

The very same thing frustrated me. Then I came across this video tonight and it seems to work.
