*Dear all:**

I have been experiencing some problems with Coot when making zone restrained refinement. I'm using Cento5, 32 bit. The problem appeared recently using Coot version 0.6-pre-1 Miramar revision 3364, but also happens if I turn back to the previous Coot 0.6-pre.

   At the terminal you can read:*
