Rich text, Quick Reports and Access Violations

I need a DB aware Memo field on a Report. I'm using the Pro version of
Delphi4 and all I can find is the rich text QR object. When I run my program
and preview the report twice, the second viewing causes an access violation
in the Richtext DLL can anyone suggest why I'm having this problem? and why
only on my second Preview of this report only? (I have 3 other reports that
are fine)
