<tr class="text" onmouseover="javascript:style.backgroundColor='#e5e5e5'" onmouseout="javascript:style.backgroundColor='white'">

This is not executed when expected. IE highlights the whole row when you hover anywhere over it; Konqueror highlights only the cell you hover and only when you hover over a link in that cell. Since the javascript is in the tr tag, i would have expected it to apply to the whole row, not just links.

Some cells look like this:
<td><a href="/horde/imp/message.php?index=713" onmouseout="window.status='';" onmouseover="window.status='Bugzilla Change Password Request'; return true;">Bugzilla Change Password Request</a></td>

This code is not executed at all. The status bar shows the link target. Is this intentional?

The code is found in the IMP (http://horde.org/imp/). My site uses a slightly customised version which I can't give out access to (it's my email).
