I've been downloading and uploading successfully on the network for awhile, but some things I'm not understanding:

1 - What does "Uploading Hash Tree" mean?

2 - Why do I see uploads continue to come in and queue up, then proceed, even well after I've disconnected. My status clearly shows Disconnected, and I'm a leaf node. Could someone explain the process?

Thanks for the info - I haven't seen this covered in the FAQ's or User Guide.
