I have a newbie question!

I m trying to make a platformer game , and i am very new at this ,and i have a problem with my background, when i hit play , it displaces to the right quite a lot , same with sprites that don t move or have any function. the background is on -1 position and on a different layer then the rest.i have my cam fixated on the char and it all works just fine except this! can anyone please please help me? :frowning:
