Thanks, I didn't know that. The changes you suggest work
so I will do that from now on.

Yes. My institution's official version is still XEmacs 21.4.6 
which I left alone in the default directory 'C:\Program Files\XEmacs'.
I put the up-to-date version (21.4.19) elsewhere,
assuming that having two versions wont create a problem (I havent
noticed anything).

Regards,

John.
