drag and drop

   I don't know if this is an MFC problem, or a ToolkitPro problem...
I'm trying to get drag and drop working between CXTPDockingPanes in my application. I have 4 panes:
Pane 1 has a CXTPTabControl with a CTreeCtrl derived class on each tab
Pane 2 has a CXTPTabControl with a CListCtrl derived class on each tab
Pane 3 contains just a CTreeCtrl derived class
Pane 4 containg just a CListCtrl derived class
I have added ON_NOTIFY_REFLECT(TVN_BEGINDRAG, OnTvnBegindrag) to my two CTreeView classes and ON_NOTIFY_REFLECT(LVN_BEGINDRAG, OnLvnBegindrag) to my two CListView classes, but only pane 1, 2 and 4 respond! The pane containing my CTreeCtrl class doesn't hit the OnLvnBeginDrag method.
Question 1 - any idea why the pane containing just a CTreeCtrl class doesn't respond to a drag?
In the 3 classes where the drag works, I create a COleDataSource and populate it, then call DROPEFFECT dropeffect = OleDataSource.DoDragDrop(DROPEFFECT_MOVE, NULL);.  I have added OnDragEnter, OnDragOver and OnDrop methods on my 4 CTreeCtrl and CListCtrl classes, but none of them are hit.
Question 2 - any idea why none of the pane contents are hitting their OnDragEnter, OnDragOver and OnDrop methods?

	Hi, If you use CXTTreeCtrl try to change it to standard CTreeCtrl.

	All of my controls derive directly from the MFC classes:- Both of my tree controls derive from CTreeCtrl and both of my list controls derive from CListCtrl.
