Thanks jcl!

More info on reonnecting: Today it happened without Sleep involved. There have been some Internet interruptions, and somehow Zorro settled into a pattern of ~30 seconds connected every 1 hour, at more-or-less exactly the same time every hour. (FYI, strategy's BarPeriod=1.) After 4+ hours of this, I clicked Stop, No, and No. Zorro posted as shown below, and cleared the User, password, and 2nd account drop-down, then just sat in Trade, Offline. I tried re-selecting the Demo account from 2nd drop-down, which also populated the User and password fields, and again did Stop, No, No, with the same result. Zorro is still in Trade mode, but Offline and going nowhere.

Then I did Stop, No, Yes. Fields again cleared. Again selected the account and fields re-populated. Clicked Trade. After compiling, same result - except this time Trade isn't entered.

This is the last bit from the log:
