Hello All: One of my students is just trying Scott's ZnO tutorial and we are finding a consistent problem when trying to work with the third project file. When we get to the point of adding an additional path, (feff0011.dat), artemis crashes with the following message: --------------------------------- The following message was trapped by Artemis: Artemis0.7.006warn/home/segre/.horae/stash/ARTEMIS.TRAPCODE(0x9652e54)/home/segre/.horae/stash/artemis.project.2/ at /usr/bin/artemis line 1562 main::__ANON__('Use of uninitialized value in string eq at /usr/bin/artemis l...') called at /usr/bin/artemis line 7313 main::read_feff('^^') called at /usr/lib/perl5/Tk.pm line 225 eval {...} called at /usr/lib/perl5/Tk.pm line 225 Tk::__ANON__('Tk::Menu=HASH(0x974a060)', 'active') called at /usr/lib/perl5/Tk/Menu.pm line 531 Tk::Menu::Invoke('Tk::Menu=HASH(0x974a060)', 1) called at /usr/lib/perl5/Tk.pm line 347 eval {...} called at /usr/lib/perl5/Tk.pm line 347 Tk::MainLoop() called at /usr/bin/artemis line 1707 -------------------------------- This is happening on all of my Linux machines. They are using my Debian packages and so I have not tried with the tarball installation. Has anyone else had this problem? I hesitate to report it as a bug until it is confirmed. In a previous version of horae, it worked fine. Carlo -- Carlo U.
