title: Have window activate previous window on activation?
body: <p>I have a program that runs over the top of the screen, I couldn't figure out how to allow clicks to the window behind it, so I have decided it's easier to just reactivate the previous window if its accidentally activated. It is not possible to tab into, the only way to activate it is to click the text on it.</p>
  <p>So, I'm asking, is it possible to find the window activated just before my program is activated? I would prefer not to do a check every couple seconds or so for the currently active window.</p>
