Description

Dual Screen setup with multi-item launchers on right screen. the popup screen does not show up above the launcher icon but on the left side of the right screen. Screenshot: http://www.pasteall.org/pic/73566

btw if the same launcher is somewhere on the left screen, the popup appears correctly.

thanks for looking into it! Roel
