>You may be closing a table manually (with a USE statement) when the destroy of the data environment object is trying to do it. Or a table may have been inadvertently closed for another reason and when the data environment destroys it looks for all the tables it opened and essentially does a SELECT and USE. If the table isn't open, you get the error.

I have stepped through the whole thing and never USE anything in my custom code.

I can open my app, open this form, close it without touching anything, and get the error. Or, I can open the app, open the form, close the form, no error. It is sporatic. I can open the app, open and close the form 10 times and get the error twice. I can't give it to my users like this. I am stuck.
