changing editor

Hi guys I am having trouble with latest release of hugs, this because I like to use "editplus" as a default editor for Haskell (I like syntax highlighting). Problem is that when I change editor on hugs, next time I restart it, it gives me a message "unable to load prelude". It seems something to be with the rewriting of editor's path. tried to find it it, but no success. Not a major bug, but it's always useful just to type ":e" to see program. don't know if just me, sine no talking to anyone. Just trying to help Ricardo Figueiredo
