The filter is applied to the cursor, and lives independently of the form. You should look into converting these forms to use Private Datasessions, so each form uses its own copy of the table, and can set up its own filters, indexes, etc. It's a little work to get used to PD, but once you get in the mindset, you'll find the effort is definitely worth it in terms of flexibility and maintainability.

>>>Hi All,
