The modify ticket owner field is no longer a drop-down, and is just a text field<br />you need to populate with a username. That&#39;s not ideal, but hey Trac seems a lot faster :-)<br /><br />The old UI experience was desirable.. but until the bug above is fixed i&#39;m out of options.<br /><br />Thanks!<br /><br /> -- Alex<br /></div></div>
