Gary,
Thanks for the diagnostic report. I confirmed what I suspect was happening, and I think I have a fix for it.
Please download and install
QRecall 1.2.0a78. After a few days, please send another diagnostic report (regardless of whether the problem reappears or not).
Note that a release candidate will also appear in the next few days, at which time 1.2.0a78 will want to update itself. Please postpone the update until you've let a78 run for a while and have sent the report.
Thanks again,
James
