I have an Access 2007 form that works fine as long as I stay in form view. But as soon as I open it in design view then switch back to form view it is invisible and the program is locked. I have to exit through task manager at this stage.
There is no code to change the visibility and the form is not modal.
I have decompiled the db and compacted and repaired it, all to no avail. Any suggestions as to what is going on?
