I attempted to do a search an advanced search on tickets, and the advanced ticket search window appeared. I then selected the calendar icon to choose a date, and that popup appeared under the "advanced search" popup, rendering it unusable.
Confirmed, and reported to devs.
Thanks much.
while they release a fix, you can set the ui-datepicker class z-index here:./scp/css/scp.css and set it to min 111.ui-datepicker { z-index: 111 !important;}
