moveItem doesnt work

Im using dhtmlxTree_pro_v16_80319 but moveItem doesnt work.

what can be the problem?

Please check the next sample … 3175919000

It uses latest version of dhtmlxtree as well, and item moving works correctly for it.  ( there are no any special requirements to use moveItem - just be sure that used itemID and mode name are correct ones)

If problem still occurs please provide more details about situation ( some kind of sample|code snippet with which problem can be reconstrcted )
