FWIW, we haven't encountered this bug in a log time now -- perhaps not since 2.0.0.9. We're using TB 2.0.0.14 at present. Our mode of usage hasn't changed, except maybe in that we use TB more frequently since I last wrote, so it looks to us like the bug is fixed.

Our thanks to the fabulous TB crew!
