As far as i know XEmacs uses mswindows-* and Gnu Emacs uses w32-*, but
the parameters seem to be the same.

I'll try those out. As for using a mouse-3 I prefer using the
keyboard, its quicker than using a mouse. I would prefer that under
windows, it is the other way around. So that any file that is not
specifically mentioned in the org-file-apps is opened by default, and
C-RET performs the system mime operation.

Under XEmacs ms windows the link file:~/.bashrc means nothing. I've
come across this before as i use my .xemacs config on a few different
platforms. If you use (expand-file-name "~/.bashrc") on windows it
might return "C:\\home\ dir\\tim\\.bashrc" and on linux ("/home\
dir/tim/.bashrc"). When combined with calling an external process is
better, especially since it also shell-quotes the string.

IIRC This works for Gnu Emacs and XEmacs.

Could i also suggest that when opening a link that ends in a / or \
that it invokes dired mode on that directory?
