Script ending randomly

Ok, I get this on all scripts sometimes..

I start it and after a few minutes it just stops and says successfully executed :o

Any ideas/

I occasionally get that too. Just re-center the Runescape window with the crosshair, then restart your script.

It was actually just happening to me while i was updating my thiever then it just stopped. I dont know what I changed or if it even made a difference but it doesnt do it anymore.
