type ahead or typeahead buffer on 2003 upgrade

Hi. We're upgrading from ms access 97 to 2003 and finding that the
type-ahead buffer in 2003
can't handle as many characters as we are used to in Access 97. I've
found this question only
once in the archives, with no response, and no entries at all in the
ms knowledgebase, so I
must be missing something very basic or have done something obscure.
Is there a setting
somewhere I have missed that can increase the size of the buffer for
fast typing ahead of data?

Thanks a ton.
