[jQuery] Is this bug in jquery???

i am using jquery version 1.2.3.
I was trying to attach hover on <area> inside <map>. but find that its
working ok in FF but not in IE.
when i try to set <area onmouseover=""> then it works for both IE n
FF.
is this the bug??
If IE supports onmouseover event for <area> tag inside <map> tag then
hover should work.
thnx
