Text field changed into memo field

Using a MsAccess database via ODBC with Delphi I have the following problem:
In Access I have a text field with 250 characters. Using this field in
Delphi 4 I see that this text field is changed into a memo field what I
don't like. I can't see the content of this field in a DBGrid anymore.
I've seen that this change happens when an Access text field (255 characters
allowed) is bigger as 127 characters.
Does anyone has a solution?
