Hello, I use the following listbox object:

<listbox id="gridUsersList" fixedlayout="true" mold="paging" pagesize="10" multiple="true" checkmark="true"> <listhead sizable="true"> <listheader label="Userid" sort="auto"/> <listheader label="Name" sort="auto"/> <listheader label="Surname" sort="auto"/> <listheader label="City" sort="auto"/> </listhead> </listbox>

The Listbox object on Firefox appears correctly, but on Internet Explorer I do not see the the label in headers columns: Userid, Name, Surname and City.
