It looks like this selects the window on every motion of the mouse.
That may be what you don't like.  Maybe it should select the window
only when the mouse moves into a different window.

Also, it seems to be completely unwilling to select a minibuffer window.
When the minibuffer is active, it should be selectable like any other window.
