Uninstalled/installed LS. Odd result: having not changed a thing, or at least that's what I like to believe, something doesn't work anymore in one of the menus of all themes. It's happens when I need to open eg the step.rc. The thing that I don't understand is that the settings should be correct since similar ones do work:

eg:
*blabla "$ThemeDir$help.html" -->> works
*blabla "$ThemeDir$Theme.rc" -->> doesn't

Text editor and browser are correctly located.

Ok, 10 seconds after I posted I found it. The rc files weren't yet associated with the text editor. I knew it had to be something stupid. :) A relief though.
