Nav Bar problems

[Squeaky]

Hi.
I thought I'd give the Nav Bar feature a go having only used repeating buttons.

It seems a bit flaky to me so I removed WD6 and reinstalled the latest version but am still getting unexpected results.

If I created a simple button with a MouseOff and MouseOver states. In its standard form - with a dummy link it is fine. Once I turn it into a Nav Bar it displays the mouse over state on the current page. I thought that this was only supposed to happen if I had a MouseDown state?

I guess I could go back to building individual buttons but that would be a shame because the Nav Bar feature could be a real time saver if I could get it to work.

Here is a copy of the file. Any help would be appreciated
