transfer queue issues

I needed to copy (not move, but create a second copy in a different folder) a set of files. I right-clicked and dragged them to the appropriate folder, and they were shown in the transfer queue with appropriate locations and destinations. Except, they're not going anywhere. All six files have timed out, and now I cannot remove them from the transfer queue. I have attempted to delete them from the queue, which gets me the normal "Do you want to do this?" prompt, but nothing happens when I say yes. I cannot upload anything else into the queue, and the buttons for Stop, Pause, and Go for the queue are grayed out and unresponsive.

This is the log for this action:

Transfer is not complete, because there is nothing in the target directory, and now it's not letting me do anything with it. When I try to close the program, it informs me that there is a transfer still in progress.
