There are several changes where this distribution develops away from classic desktops: - maximized windows use panel instead of title bar - global menu - overlay scrollbars I guess the last two will stay as inconsistencies for a long time (if not someone manages to get the windows menu into the panel), but I thought that maximised windows shouldn't behave different than they used to. However I experienced strange behaviors with many applications: When a window is maximized (= title bar is replaced by panel), the cursor position seems still to consider the height of the title bar. Thus a click on a toolbar icon results in a click event on the icon above; a click on the upper toolbar icon results in a click event for the menu. When you click on the menu, the whole window "jumps out" of the panel and displays as a normal maximized window below the panel. This is the case for Google SketchUp, ACDLabs ChemSketch, etc. This is not the case for Mozilla Firefox 3 (Windows version). Has someone experienced similar things? Is it likely that it can be fixed sooner or later in Wine, or is it rather an issue for Ubuntu?
