Nav bar creation in WD6 - stretchy button

[DocRock]

I built a stretchy button in Xpro5 and gave it a mouseover effect. I cut and pasted it as XaraX document in WD6 then created the navbar. On the WD6 canvas it displays with the mousever color rather than the mouseoff. When I preview it the mouseover effect doesn't work and is not linking. I tried moving the mouseover and mouseoff positions in the Object Gallery and other problems arose. I'd appreciate if someome look at the attached dot web file and help me find where I've gone wrong.
