I created a Keyboard Shortcut (Shift+P) for using the "Page Layout" after model to sheet, because it is always needed to change the scale to 1 and enable "Show Page Breaks in Drawing Window". So far. But when the Page Layout dialog called with the Keyboard Shortcut, and the setup finished, is it no longer possible to activate a draw view with the mouse pointer. Only when using concept explorer and making the layer invisible and visible, it works again. When calling the "Page Layout" via the menu bar it works without error. It seems it have to do with the Keyboard Shortcut.
