CHANGE Error msg to always pop up
CHANGE Error msg to always pop up

Before, we were relying on what is in `self.log` to determine if we
should get something from the error queue. Now, as long as there is
something in the error queue, it will be gotten.

Technically there isn't any real change (queue and log should always be
synchronized).
