When you click the home, history, model , etc links you will notice the rounded corner for the home to disappear, if you mouseover it, you'll see that it seems to have repositioned too?

I take it no one knows the reason?

I don't have anything helpful for you regarding this, other than to say that yes it definitely looks like a bug.

It appears there are a number of JS errors being thrown when clicking the tabs, perhaps these are related to the mispositioning.

I'm having the same issue. It looks to be related to the zoom problem. When PIE draws it's rounded corners they don't like to move! eg if you show a panel above a curved element using js, the contents of the curved element move whilst the curves remain in the same place

See attachment for an example

This does seem to be the case. On my website, something is changed below the element though.
The weird thing is that the other top tabs are not effected at all, "About Us" "Contact" and "Brands" all stay put and dont move. For some reason the Home one does.

When I do zoom using IE, the repositioning seems to be fixed until I click another link though.

I am pleased this is fixed in beta 3.
