I created a database with 1 form about a year ago. This database has no data as yet, but I wanted to modify the form. When I make any changes, it becomes corrupted. I will either loose all signs of the tables in the "shutter bar" or the form will not open after it has been saved. The change can be as little as moving a divider line up or down. I have created a lot of forms in the past with earlier versions and have never had this problem. This is a simple database with no back end and is only on my computer. Does anyone have any ideas why this is happening?
