Hi Marco!
Normally I would say, "QxDom.getComputedPageBoxTop" should respect
scrollings, too. This was the original intention. If this isn't working
we should fix this there instead of changing each class which is relying
on the features of this method.
Is this problem reproduce able cross-browser? Have you tested this in
Firefox, IE and Opera?
Thank you for your support.
Sebastian
