A workaround for this issue is to ensure that all your screens have the
same size. This can be easily achieved by using a common background,
like Browser or Window widgets. The best way to manage this common
background is to create a base screen and then include it as a component
in all other screens.
Let me know if this works for you.

Yes, I've inserted a panel on every page, surrounding all elements. That was a bit cumbersome, but it worked!
Another question: is it possible to print all files at once?
