Losing Connection To Paradox Table

Hi,

I have an application with 6 paradox tables. At some point in the program
one of tables does not want to show its content. This happens when user
switch between different  forms. The only way to display records again is to
exit and restart the program. I  open the table in the form On Create
handler and close it in the On Close handler. All the tables and their
associated data sources are centrally located in a data module.
Thanks,
