Chris, there is another feature of ADW that I love but it can bite you if you don't know about it. Where you have your five program icons, you can "flick" those icons up to reveal a hidden second drawer of icons. I first did this on my Android phone and thought I lost all my icons. I had trouble flicking the menu back down and could not find my app drawer (just like you). So I made sure I added the Open/Close to that second row of icons. I put a market icon on there too. On these devices it seems easy enough to flick up but not down. If you click on Settings, then More, then ADW Settings, you can disable the hidden drawer.
