first editor is taken by default

[bon-ami]

double commander 1.1.17
windows 10
F4MM 1.42

press F4 on a non-text file, such as exe, in double commander. and notepad2-mod runs to open it. (notepad2-mod runs for txt files, too, which is as expected.)

• Settings
  • Background mode=F4
  • no TC path
  • INI path points to doublecmd.ini
• Editors
  • notepad2-mod = txt,log,xml (not set as default)
  • notepad = txt,xml

That is what is supposed to happen - the first editor is to the default which means that for any extension where there is no editor defined, it will use that editor. So it can't find any for exe then it will use the first entry.

The same would be the case if you weren't using F4MM and only setup - notepad2-mod.exe in your case - as editor in DC, it would then open the exe files in notepad2-mod.exe too.

Unless I misunderstood your comment.
