Hi, Because of bug #23189 (https://gna.org/bugs/?23189), I'm considering depreciating wxPython 2.8 in relax. As it will still be present on many systems, I am thinking of implementing this as follows: - The dep_check module gives a warning when the program is started that the wxPython 2.8 version is buggy and can result in segfaults. - Disable the GUI tests. The new General.test_bug_23187_residue_delete_gui GUI test causes the GUI tests to regularly segfault on wxPython 2.8. The problem is in the tree GUI element of the spin viewer window. The bug was solved in wxPython 2.9. - Updating the dependencies in the relax manual (http://www.nmr-relax.com/manual/Dependencies.html) and the website (http://www.nmr-relax.com/download.html#Dependencies, though this is already done) for wxPython 2.9. Any suggestions are welcome. Regards, Edward
