As I understand your problem you're trying to select a bitmap background,a bitmap hippo and then vector skates, and then move them around the page as one group is that right?

The only way I could replicate the problem was to put one of the objects onto a separate layer and then make it uneditable. If everything is on the same layer then either the marquee or select all should select everything, you could then try Grouping (Not Combine or Add Shapes)the objects to get them to stay together.

If this isn't the solution I'd recommend posting the question on the Xara X group.

Hope this is helpful
