When (ispell-buffer) is underway in one frame, and the displayed buffer in another frame has different/additional menu bar items, selecting that second frame doesn't update the menu bar. However, clicking on the menu bar *does* trigger a change to the menu bar categories, which means you may click on the wrong item! (i.e. the menu bar item under the mouse pointer may not be the same with or without mouse-1)
