Using external Find tool?

Hi,

I'm trying to get Directory Opus to launch "File Locator Pro" instead of DO's built-in Find tool. I found an option that may allow this but I can't figure out how it works. The option is in:
SETTINGS -> PREFERENCES:
MISCELLANEOUS -> ADVANCED -> find_extension_func

I put the full path to File Locator Pro in that field but nothing has changed; DO still launches it's built-in Find tool. I tried the Advanced Keyboard Map option for the "Find" command but there doesn't seem to be any applicable arguments to launch an external find tool. Anyone have any ideas? Thank you.

If you want File -> Find or Ctrl-F or whatever to launch another program instead of running the Opus Find command, edit them to run the other program.

i.e. You don't need to give the Opus Find command a special argument to tell it to run something else; instead, tell Opus to run something else instead of the Opus Find command. Each menu/button/hotkey can run external commands as well as internal commands.
