It seeems as it allways happens when a windos pops up or the window with the focus gets closed. Instead of focusing the next window under the mouse, the focus flips to the next screen (dualhead setup).
Not exactly the same, but related: if I have focus on DISPLAY :0.1 and there is some activity on some other workspace on :0.1, I use M-k k to switch there. But when I M-k k to switch *back* to where I was, it moves me to :0.0.
