That's the solution I end up using. It works quite well both on POSIX  
systems and Windows :-)

It might be a holdover from the old days but it's quite handy for

On Windows is a bit more work as a Logtalk user needs to duplicate the  
installed shortcuts and erase the "Start in" field in the shortcut  
proprieties. The edited shortcut can then be copied to your project  
folders. Also, in the case of Logtalk, if no settings file is found in  
the startup directory, then the Logtalk user folder is searched for a  
settings file. The Logtalk user folder is always defined using an  
environment variable.

Thank you both for your suggestions. Cheers,
