Simpleviewer + SWF Tools -> Editing Colors + Dimensions doesn't work?

Hi all

I'm using SWF Tools 6.x-2.5 & SimpleViewer v2.0.1. I've renamed simpleviewer.swf from the simpleviewer.rar package from the simpleviewer site to viewer.swf and placed in /shared/simpleviewer.

If I go to /admin/settings/swftools/simpleviewer, changing settings under "Dimensions" works fine but changing settings under "Colors" and "Navigation" does nothing?

I fear I may have a too recent version of simpleviewer? What is the problem here, I can't work it out? Also if someone has another method for specifying colors/navigation I would appreciate it.
