Why isn't any of the mouse over test showing up??
I see your problem and what I tried was (using the code below) was put Goat Paddock where ( title="" ) is and remove from window status. This seemed to work for me in FF and IE 7. I don't know why this is like this but instead of it showing the mouseover like it should, it showed the alt or title text instead. This is a work around sorry not a fix..
<area shape="poly" coords="742,459,652,398,529,534,593,588,742,460,742,460,740,460" href="" alt="" title="" OnMouseOver="window.status='Goat Paddock'; return true" OnMouseOut="window.status=''; return true">
Have a great Christmas.
