cmd-tab behavior on Mavericks with multiple displays I have a MacBook with Cinema Display, I have my dock on the MacBook screen side and my menubar is set to Cinema Display. In 10.8 this worked well, when I pressed cmd-tab to switch apps the task switcher would come up on the "main" Cinema Display.

In 10.9, however, it's always on the MacBook's screen, very annoying. Is there a setting I've missed?
I believe this coincides with the Dock's location.  Just tested it on my MacBook Air, connected to a non-Apple external display, and whenever I moved the Dock from screen to screen the Application Switcher would follow.

You can summon the Dock on your big display by dragging the cursor to the bottom of it's display, essentially dragging down at the bottom.  After a second the Dock should pop up.  Once the Dock is on the desired display press commandtab to summon the Application Switcher.
