Can't edit Baldur.lua file to enable console commands

Every time I try to edit the Baldur.lua file it does not save the changes, almost as if I didn't have WRITE privs (only READ privs). However I've already checked the file and it is clearly marked as having full control.

I've attempted to edit the file multiple times. Then i save the changes, close Notepad ++ and reopen the file (without going into BGII: EE in between) and my changes are gone.

I've run out of ideas on what could be doing this.
