arglborps...nope, that ain’t it. I’ve left it, gone and taken a shower, got dressed, come back 30 minutes later and it’s still spinning.

but I think JKT is on to something. I deleted each file that had the word ‘history’ in it and it then exhibited the behavior arglborps mentions. Spun for a bit and then returned control. Guessing one of those files got corrupted.

Thanks, folks, much appreciated.
