Uwe,
difficult day? smile

BIAB is a pretty complex software, so I think it is overly optimistic to expect it to work flawlesly. I am actually surprised how stable it is. (Comparing with crashes in other software). I agree that it has quite a few bugs and strange aproaches, but I think the wise thing to do is to provide 1-2 sentence for each issue you are having with example (track that you have issues with) so people can replicate them and confirm. A lot of bugs (not all) get fixed when discussed here.
