Thanks for the feedback on the various trees.

Just discovered after getting the drag and drop in InfoTree to work correctly
on a smaller dataset (~500 records), it totally seizes up on the full table
(35,000 records). Also, its definitely not a good idea to have autoexpand set
true for drag and drop, unless the timing interval is set much higher.

What size file have been loading when you say "large?"



Looks like I'm off to trying yet another TreeView!
Could I back channel you about the VirtualTree to see how you set it up? So,
did Paul upload a new IB_VTree?
