Dear Coot, I recently installed Coot version (0.6.1 64 intel) on a iMac 10.6. using Fink , 64 bit (Fink installed via bootstrap).
I used the command sudo apt-get install coot and everthing seemed fine. On entering command coot, software loaded successfuly. However after I logged out and then logged in I couldn't re-load Coot. Thanks, David.
