Keep Preview window on top of another window?
Is there a simple way to keep the Preview window on top of another window? Basically what I'm trying to do is compare pictures on my hard drive to pictures on a webpage in Safari. I keep having to click back and forth between Preview and Safari because the Preview window wont stay on top. I read that the program Afloat should do the trick and I downloaded it but I don't seem to be able to get it to work.
