DW "Set Nav Bar image" behaviour in IE5 for Mac

[actualsize]

Here's a weird one. I have a site in development in which I have used the "Set Nav Bar image" behaviour in Dreamweaver. When I look at it in IE5 for mac and rollover the images which have had the behaviour applied the browser acts as though the document is getting longer. The scroll bars change as though there is more and more after the end of the document, but there is nothing there! Does that make sense?!

Hello actualsize!

I've just seen your site with IE5 on PC and found everything OK. So problem could be in JavaScript for NavBar that badly works on Mac. But I'm sure that this script must work on Mac.

I couldn't really help you but just inform you that on PCs it works fine.

Good Luck!
