<Map> problem i Firefox

hej eksperter,

jeg sidder og øver mig i at kode lidt, og faldt over den smarte <map> kommando, jeg har set det på andre sider hvor det virker, men det virker bare ikke for mig i firefox. (Virker helt fint i IE7)

I kan se koden her.

<tr valign="top">
<map name="Map" id="imagemap">
<area href="Iframe_Frontpage.asp" target="content" shape="rect" coords="3,37,93.69" title="Frontpage" alt="Frontpage" />
<area href="Iframe_Rooster.asp" target="content" shape="rect" coords="94,37,168,69" title="Rooster"  alt="Rooster"/>
<area href="Iframe_MemberList.asp" target="content" shape="rect" coords="169,37,262,69" title="Members" alt="Members" />
<area href="Iframe_Forum.asp" target="content" shape="rect" coords="263,37,342,69" title="Forum" alt="Forums" />
<area href="Iframe_About.asp" target="content" shape="rect" coords="343,37,434,69" title="About" alt="About us" />
<area href="Iframe_Contact.asp" target="content" shape="rect" coords="435,37,510,69" title="Contact" alt="Contacts"/>
</map>
<td height="75" colspan="2" rowspan="3"><img src="Pictures/Menu01.gif" usemap="#imagemap" alt="Menu" /></td>
