When creating an appointment, opening the flap, chosing the participants icon and clicking on "Select" a cute qt window is shown, which sticks to the flap and unfortunately has some rendering issues. Also, when there is no conflict, the "Solve..." button appears active, but unresponsive. Obsered in 4:4.5~20100920.1177660-1maemo1.1177547 and earlier versions.
