Hi 

This is unlikely to be the problem!! The colour depth problem is caused by
a problem in the xdl_view libraries (which should be fixed by Dave Love,
see his posting on this newsgroup a few weeks ago).

This fixes a problem which people have when their machines _don't_ hae
128Mb swap (it allows users to process enormous images; the fix above will
allow most users to process most images and have smaller swap space - I
think!!)

it's what we're here for!

Can I just repeat something that I've posted before on this BB? If you
have problems with mosflm (especially with crashes and hangups), the
people to contact in the first instance are Andrew and/or me; except when
we're both out of town, we have the fixes to hand!

Oh - BTW, _before_ asking anyone, it's worthwhile having a look at URL
http://www.mrc-lmb.cam.ac.uk/harry/mosflm, which has fixes for numerous
problems and hints for installation. It's not comprehensive, but I do have
answers to most questions there.
