I’ve received a couple of e-mails in the past week from people trying to use zDragDrop with a strict doctype. Apparently, I forgot to add the “px” on a couple of style measurements and that was causing the library to fail when using a strict doctype. So, I just quickly updated zDragDrop to include this fix (thanks to Pawan and Alan for pointing it out). This updated version is available in the Downloads section.
