No shit - that figures. I never asked for those sqlites, I'm sure they were introduced long after I became dependent on Thunderbird. Nobody ever warned me that I was now a janitor! - I don't think I should need to know about sqlite admin conventions to install and use TBird, and the TBird website doesn't make much noise about it. TBird seems to propose to compact this folder or that from time to time; so I assume it's looking after that, and my folders are in the sort of compaction ranges I've set. Dammmit, I had no idea that sqlites were supposed to be vacuumed. I need a robot sqlite vacuuming machine, I'm too old for hard work.
