Although the real screen size is 800x480, the usable screen size is less whatever system trays consume. So 'autosize' refers to opening a app so that it is no larger than the usable size.Look on this page for how to set options according to group tags. My set up is to open things without borders or window decorations since I don't care to use the pointer on this laptop (and certainly not the touch pad on my other laptops) and navigate as much as possible by keybindings. The principle is the same even though you probably only want it to maximize. As you can see by the screenshots, though, there's no need for the title bar or border if you maximize your apps (some need tweaking to work right because they start via script). The GROUP tags I used in those shots are shown about midway down the page. http://lucky13linux.wordpress.com/dsl-rel....wm-mods
Edit: You may also want to adjust your layer settings. Apps set on default layer settings will not cover the tray(s) if the tray(s) layer(s) are set on default settings.
