I'm getting these same strange results in various folders. I create a page using IQ page pack. I add HGM to it. The HGM extends way, way to the right, showing content from all panes in the initial pane's view, then clicking on the other panes glides in blank content.

Don't know what I'm doing wrong but it happens repeatedly.
