Ideally include a backtrace, but at the minimum you should include the operating system and version of coot that you are using: $ coot --version-full Having said that, I don't really follow what CCP4 do to Coot before they distribute the binaries. Official coot binaries are tested before publication - so I'd recommend you use those. It goes without saying that I can't reproduce the problem that you mentioned - and even CCP4's build of Coot 0.8.7 (on Macintosh 10.10) seems not to have this problem. http://www.chiark.greenend.org.uk/~sgtatham/bugs.html Paul.
