Very odd one. Running SQL Server under XP, with Access front end using ODBC. All works fine, but one particular table has a field Company, nvarchar(50), nulls allowed. It used to be fine, but if I try and add any record (or modify an existing one) with the contents starting 'Tow' it fails with an ODBC timeout. I can't see any significance of this particular word!! Any help much appreciated.
