Rene,
I have been able to protect the browse from the form tab. I am looking to protect a form procedure but following the docs does not seem to work. At no point do I get a key on the browse. Do you think that the tab might have something to do with it? I have tried to do without a tab but it still ends up with a '' for tab.
I could try assigning a specific value to a group and testing in the form such as Bruce does with the supervisor in the menu for Security but that will take control out of the hands of the supervisor... dunno.
