Move the parent window so that the insertion point is under the Dock or the bottom of the screen. Display the autocomplete list and you'll notice that the menu appears either under the Dock or off the screen. In Windows, the menu repositions itself so that it appears completely on screen.
Another bug is if the autocomplete list is visible and you move its parent window, the list stays in its current position. I believe it should be dismissed.
Fixed most cases of off-screen autocompletion with [11e6b6]. However, there are some situations in which the autocompletion still doesn't move on screen, notably when the window overlaps the edge significantly.
Cancels any autocompletion or calltip when the window is moved with [3712de]. Note that this is for the NSWindow containing the view, not when the view is moved within its window,
