Helen,

The offending statement is:

(form.Components[i] as
TIB_Grid).DataSource.DataSet.FieldsDisplayWidth.CommaText;

It was in my save form parameters to an INI file.

It runs fine on any computer which does not have Firebird installed, so I
not sure it is failing on a call to GDS32.dll which does not exist at all on
the other machines. (I could be wrong though.)

This seems more a problem with IBO ~ Firebird 1.5 interaction problem.
