Disable the RichEdit beep?

I have a pair of RichEdit controls that I'm using to page through
segments of a larger text block. There's no problem going forward, but
when paging backward, I get a beep when the i-beam is set back to the
top of the control. Does anyone know how to turn off the beep? I've
searched through the Win32 and Delphi4 help without success.

TIA,

Tom Malcom
