1415 frames; once the frame is created, it sticks with its assigned

1416 minibuffer, no matter what this variable is set to. This means that

1417 this variable doesn't necessarily say anything meaningful about the
|
|
|
1418 current set of frames, or where the minibuffer is currently being
|
|
|
1419 displayed.
