>The objref utility found no dangling objects. This is a cool utility I will use again. I also made sure that all cursors were closed before I tried to release the form. I wasn't updating or buffering in this form, so there were no open transactions. The fact that the grid has the focus seems to be the problem. I added code to put the focus back on a command button each time the form is activated, and the C5 went away. I can make it come back by clicking in the grid, then closing the app from the menu. I guess I just won't do that. If you have any other ideas, let me know. Thanks again, Deri

You can still get a "hanging" datasession, even if you've closed all the cursors/tables manually. After you've run your form, can you get access to the command window? If you can, enter the word "SET", and see if there are any datasesisons listed as "unknown".
