The application I am developing has a very annoying problem. One of the forms, frmJobs, closes itself from time to time when I try to edit, or close another form. There is no link between the forms, each is standalone though they do draw from the same tables in a linked database. I have no idea why. E.g. a few minutes ago I opened another form in Edit mode and the instant I did the Close Event of frmJobs executed and the form closed. It doesn't happen all the time, just often enough to be annoying. Any suggestions?
