Hi Jerry,

> at the peak hours, when updated the windows always shows open table form.

This sounds like there's an error opening the tables which is handled locally but not resolved. This would happen when a routine returns .F. because it couldn't open the table, but the calling code ignores this error value. A subsequent SELECT statement would then open the table dialog. You can use SET TABLEPROMPT OFF to avoid the dialog. Instead you would then get an error message on the SELECT statement which might help you to find the actual problem.
