I have never had a problem with Access 97 either.  Did you fill the fields
with 255 characters, or just have the field definition?  The limit is based
on the page size.  A field set to 255 characters with 10 characters in it
takes up 11 characters.  Same if the limit was set to 10.

Having never heard this before, I created an Access table with 9 text
(255) fields and successfully added a row. Then I decided to add some
more fields to the table, all text 255. I quit at 20, where I was able
to add and edit a row. 

This is Access 2002 so your results may differ. In this version, the 2k
limit is no longer. The database is Access 2000 style, so this must have
been true then too.

"Unnecessary" size restrictions on fields ensure that a record can be
saved. 
  If you have more than 8 text fields at 255 characters per field,
Access 
will refuse to save the record.  Have you forgotten the the 2k character

limit on record size in mdb files?
