Indeed weird.

I'm coming to the view that putting stuff in a separate partition was a bad idea, so I think that, before I waste any more of your time, I will move the contents to the same partition to make sure that this is not 'operator error'.  And I have a high priority task on my desk too.

After making changes to a jamfile should I always do b2 - a  (I think I have).  Do I need to repeatedly use --reconfigure?  b2 headers?

Thanks for help so far.  I'll get back to this when I've moved and double checked.
