> *Starting Coot*
> When I click on the Coot icon in the Phenix gui no window opens but I can see the processes: coot, coot_build_phenix_coot.csh and coot-real running. In fact coot-real consumes 100% of the cpu of one of the cores. What I find really weird is if I look at the processes with the system monitor gui and right click and 'kill' coot-real then instead of killing the process the coot window opens. At the same time coot_build_phenix_coot.csh disappears and the cpu usage drops to zero.

That sounds like a startup-script problem (race condition?). When you
send coot the TERM signal, it stops waiting for communication and gets
on with starting up - presumably as it would if you started it without
Phenix (if one can contemplate such a thing).
Another option might be that it is somehow picking up an old coot - and
the communication dependences are not in place - however, I thought the
Phenix gui guards against this possibility.
