I changed the "Active Image Width" parameter from 90% to 45% and now the vertical frame lines are offset to the right by a few pixels. When the page first loads the picture and frame lines are aligned correctly but after the first "slide" the picture and frame lines are offset.
See new 45% offset version at http://www.westernbaymuseum.nz/
See original 90% correct version at http://mokoconsultants.com/wbm/
A solution to this would be greatly appreciated.
I found another forum post and tried that solution - it made no difference.
Please try removing this line:
To see if that changes anything.
