Yes, I am still seeing the Server XXX has disconnected... message. But more intermittently.

I am moving messages between folders of the SAME account. For example, from the "Inbox" folder to a (sub-) folder under the "Archives" folder.

I'm moving any where from one message to dozens at a time. I am not moving entire folders.

> > c) It causes a very annoying UX issue (and possibly serious a11y issue) in that it is hard to grab and drag the splitter line that divides the message list pane from the (selected message's) header area. This appears to mostly be due to the fact that when the "Server ... has disconnected ... " message appears, the application, as a whole, appears to continually attempting to get/download messages. When it is doing that, I see (on the Win 7 client): a continuously animated icon on the "Inbox" tab; and the mouse pointer changes to the 'with hourglass/active state', when it is over everything but the actual text of the selected message. The mouse pointer state makes it hard to discern the pointer's hot spot, which makes it hard for a user (even with 'typical' vision and fine motor control) to grab the splitter bar!

Right now, this issue is not showing up on my Linux (Mint 18) machine, running TB v.68.10 (64-bit). Nor on my Windows (7) machine, running TB 81.0 (32-bit). On the MacOS (Yosemite) machine, running TB v64.11 (32-bit), the animated icon shows up briefly, on the left side of the top-level tab which has the name of the selected mail folder. E.G.  [in-box icon|spinner icon] Inbox.

Hmm . . . my first attempt to capture the TB session in a log file did not work. Will try again.

I'm not sure how to verify that. For the email account that I am using, in "Account Settings" - "Synchronization & Storage" - "Message Synchronizing" the "Keep messages in all folders for this account on this computer" checkbox IS checked.
