Thanks Mike,

I've double checkd in dbcheck.cpp in both versions (0.21 fixes and trunk)
that I've checked out and both are on 1212 - so I'll give it a try.  I've
been using trunk (very successfully) for over a year, but thought it might
be a good time to take a breather and use a stable release for a while.  It
seemed like the perfect time to jump off the trunk treadmill, and I was
worried that by the time the official release happened trunk may well be on
a newer schema and I would have lost my window.  Again - I'm assuming
(always a bad thing) that there should be no other major 'gotchas' going
from trunk to fixes (given both are on 1212).

I'm pretty sure I'll miss the neat features that keep being added to trunk,
and like a crack addict will come back to trunk within a month after release
though!

Best regards,
Nick
