Decision cube and ADO Widestring Bug??

I have a situation where i have to use ADO talking to Access97 using Delphi
5 enterprises decision cubes.
I have no problems with Number fields but if I try and use a Alpha field I
get a error message back to say that Widestrings are not supported in the
decision Cube.  Is there a known workaround? if not please can we have it
fixed ASAP.
