Rad,

I can't be sure if this will help, nor can I fill in the details right now,
but:

I think you could set a trap for the enter/return key in some event like
w32HKeyDown, or w32HKeyPress, for the RichEdit,
and then make the routine have a return if the enter key pressed, 
which should/might make the enter key be ignored.
(ie, if keypressed equal "enter" key, then return from procedure)
