This is the latest released build, I think, 1447.4.
It only started happening this week, I don't remember making settings changes that could cause this (but there are lots of things I forget after a day or two!

Anyhow, any advice would be appreciated.
P.S. Is there a way to keep a running log of messages in the session log window? The log file option does not store the back-and-forth messages between client and server, just a record of files uploaded and downloaded.)
