I have a layout that I did the other day and I can not get ANY shadows to show up on it!! I have restarted my laptop twice, I have tried CS5 AND PSE10 and nothing...flat flat flat! What else could it be???
btw, you can create a Workspace so you can save the windows you use in CS5. That way, if anything gets turned off you can just click on the Workspace you created and everything will get back in place
