After moving with alt-drag and saving then it re-opens correctly each time, so it has never been an issue. I think it is an attempt by pd to keep the canvas areas aligned consistently regardless of platform, but it doesn't always work so well. So ... Openbox allows applications and users to place their windows badly if they insist, you had better stick with something a bit heavier if you need more discipline applied. It does use its margins as a border for maximise and for 'edge resistance'. Experimenting with xfce and openbox ... pd saves the position of the top left of its inner windows (excluding the decorations and menu) and their size in its patch files .. then a window on openbox is opened exactly there if this inner window would land within the display, otherwise a clumsy guess at placement and size is made. Xfce4 over-rides this if part of the window is outside the set margins, and moves and resizes to fit. Xfce4 always pushes the whole window decoration out of the panel area and won't allow a window to be dragged too far outside the margins. I think it is a Pd issue, it is trying to place windows manually rather than giving the WM appropriate hints. Also the WM_CLASS window property doesn't seem to be properly set, so it isn't dealing with the whole WM thing correctly at all, probably trying to avoid different WM and OS decisions leading to different layouts. There will be others which ask for awkward positions in a way that Openbox does not fix up. Simon
