Follow-up Comment #1, bug #23187 (project relax): I cannot reproduce the bug with the following steps: 1) Start relax in GUI mode. 2) Open the prompt window. 3) Type: pipe.create('test', 'mf') residue.create(res_num=1) residue.create(res_num=2) residue.delete(':2') 4) Close the prompt window. 5) Open the spin viewer window. This is on a 64-bit GNU/Linux system with wxPython 2.8.12.1 (gtk2-unicode). Maybe it is operating system dependent, wxPython version dependent, or there is something strange with the data. A system test which triggers the bug will be able to isolate the issue. _______________________________________________________ Reply to this item at: <http://gna.org/bugs/?23187> _______________________________________________ Message sent via/by Gna! http://gna.org/
