Image pushed beyond screen

I have a series of forms that has an image in top left corner. When there are actions in the action bar all is fine. However, when there are no actions the image moves about three inches left and half of the image is now beyond the left margin.

Any ideas why this very irritating problem is happening?

(I have noticed that the first document I open from a newly opened view is on the far left of the form (the scroll bar is on the left). If i then open that same document again straight after it is now opened in the center (the scroll bar is in the center). Very strange, and extremely annoying behaviour)

Regards
