Yes - in tests, the DnD now seems to work OK, more or less (I still
have other issues however, see other posts.)
The main kicker with this now is that as the drag happens, the drag
displays a tooltip with the contents of the drag displayed - but what
I am dragging is a long text string full of cryptic information used
to define the dragged entities, and it just looks very odd.
I'm guess that my end users will not like that - is there any way to
suppress that behaviour and not display the text content during the
drag?
