I have tried changing the default application and adding additional applications to the open with dialog.

It seems that some file extensions are no longer working with remote buddy file browser which I assume could be an issue with my launch services.

If named .txt or .avi the file browser will navigate to the equivalent of an "open with" in the remote buddy file browser but if the file has a .command or .sh extension remote buddy does not allow me to open or execute the file and seems to refuse to hand of the file to anything.

I will reset launch services and see if that helps.

Cheers
