Kirk Bate reacted to Mathematics in [Bug?] Prior scan data and settings not preserved on update
Same thing happened to me, now twice. There were two updates within the last week, so it seems. Every version of Scanner was the latest at every point of the software running on all my systems. Both times, the previous scan data, after the update, was purged. I don't see this to be such an essential problem but I'm just reporting the observation.
