> The mouse pointer will now be to the right of the window frame; with
> normal window managers, this doesn't matter much, except that a "resize
> this window" cursor might be shown rather than the usual one, but with
> tiling window managers, the cursor position may correspond to another
> window, which is then raised and wrongly receives keyboard focus. This

> The attached patch fixes things, by moving the mouse pointer to the last
