Version: (using KDE 4.4.0) Installed from: Archlinux Packages I'm running a dual monitor setup. Using the nvidia driver with nvidia's twinView. When maximizing a window, KDE properly maximizes it to the current screen's size. Imagine the following screen vertical edges: |1 2||3 4| (so edge one is left of the left display, edge 2 is the right edge of the left display). When I place a panel on edge 1 or 4, maximizing a window will work properly, and not cover it. When I place a panel on edge 2 or 3, maximizing a window will ignore the panel, and place part of the window contents under it. I've noticed this in KDE 4.3 and KDE 4.4.
