[jQuery] dynamically appended table-rows in loose hover effect in IE

[ravenel]

I am loading <tr class="even"><td>data</td></tr> dynamically with
jquery load function  e.g.:

.even{
   background-color: red;
}

.even:hover {
   background-color: blue;
}

jQuery("tbody").append(data);

that works perfect in FF, but in IE the hover css for the class="even"
is not interpreted anymore in IE for the dynamicly added rows.

any ideas or known bugs and solutions?
