Stop Master Detail Popup

I have several (6) master detail relationships... some have quite a lot of columns.

I have the linking menus to take the user to the detail record,

and I don't want the 'POPUP' to come up.. because it goes off the screen

and also covers up the menu links.

First, how do I turn this off ? .. and Second.. can you please add a check box option

to turn this off or on for each detail table ?

Thanks.

Paul.
