External applications to open in specified lister

There's a registry hack to do this, although it may produce strange results (e.g. with system folders like Recycle Bin) in places and isn't officially supported/recommended. You can always change things back if it doesn't work for you, though.

Edit: Here's an alternative registry hack in case it's better. (Uses the last active lister.) Also note the warning from Greg @ GPSoft that this definitely isn't supported/recommended. :slight_smile: (But until there's a proper way to do it, it's the only option I know of.)
