Drag and drop highlighting.

[cwr netcom co uk]

I'm trying to highlight the target on a treeview drag and drop operation,
and while there's TREEVIEW_DROP_INTO_OR_BEFORE and TREEVIEW_DROP_INTO_OR_AFTER
there's no TREEVIEW_DROP_INTO, which is what I want.  I'm trying to avoid the
highlighting of the row separators, and have just the row itself highlighted
when a drop on the row is valid.

Is there any way to suppress the row separator highlighting, and keep the
row highlighting?

Thanks - Will
