Beyond that, if you've created cursors in things like comboboxes but they are not listed in the DE, then they may not close causing the datasession to be unable to close because a cursor still exists in it.

Thanks to all for the many responses. There are numerous threads going about this error, many getting it for diffent reasons. For me, I have gotten rid of the errors (for now) by getting rid of the nav toolbar launched by my doform() method of the app_application (VFP6 App builder). I am also removing most of the calls to this objects methods. I thought I might add some feature to my app by using this framework. Some Feature were added alright! Anyway, serveral weeks lost fighting it, and a deadline approaching way too soon...

I'm keeping it as simple as I can now.

BTW, I wasn't doing transaction, and the error would occur without touching a field. No editing, nothing.

Thanks again for all your help.
