Dear mcstas-users,

If you ever encounter the below error from mcgui versions < 2.3 (forthcoming release),

Tk::Error###: This shouldn't happen at /usr/share/perl/5.18/Text/Wrap.pm line 84.
 Tk callback for .toplevel
 Text::Wrap::wrap at /usr/share/perl/5.18/Text/Wrap.pm line 84
 main::run_dialog_create at /usr/local/bin/mcgui line 752
 main::run_dialog at /usr/local/bin/mcgui line 824
 main::my_system at /usr/local/bin/mcgui line 985
 main::menu_run_simulation at /usr/local/bin/mcgui line 1320
 main::__ANON__ at /usr/local/bin/mcgui line 1752
 Tk callback for .frame1.button
 Tk::__ANON__ at /usr/lib/perl5/Tk.pm line 251
 Tk::Button::butUp at /usr/lib/perl5/Tk/Button.pm line 175
 (command bound to event)

- then the fix is to replace the function run_dialog_create in your mcgui as described here:
