We should have meetings... the first step being to admit we have a problem
(or to quote Homer 'no no, that's too expensive - just don't do it again'
; ).

Actually, it just ocurred to me that I probably got it from 'fulcrum'.  Now
don't tell me there isn't an 'r' in that one either...

Finally getting a chance to get immersed in the heightfield stuff...
