>yes, i'm using select sql ...into cursor...and they not all the time are deleted, that is what i/m asking if i do something wrong or exist some command to do the deletion...

That's what I'm trying to find out. There is no command to delete them because VFP should delete them in the normal course of clean up unless there is an error.

When they aren't deleted, is your application crashing in some way? Do you get an error? Do you have an error trap that would mask an error if you had one and you wouldn't know it?
