use the message box oir aprepare a button with this script:

set the externals of stack xyz to "MacExternal.bundle" & CR &  
"Windowsexternal.dll"

So you have both exteranls set :-)

Exactly, you can do by "start using xyz"

A good idea is to use an (empty) substack "xyz", so you simply use
something like:

on openstack
    set the externals of stack "xyz" to "MacExternal.bundle" & CR &  
"WindowsExternal.dll"
    start using stack "xyz"
    ...
end openstack

This way, every open stack can use the external.

Hope that helps
