Subject: RMagick's #display (focus issues) - off-topic?

I was playing with a little software idea last night and ran into
difficulty.

Actually, I could start an email with that sentence almost every day.  ;)

I wanted a little image-processing tool and felt that Photoshop was
massive overkill (also, I don't have it anymore, and it's expensive).

So I thought: It might be fun to write a little semi-interactive program
with an old-fashioned interface.

This is Mac OS X, fwiw.

The basic logic flow was:

   Read an image file
   Loop:
      Read a command via gets
      Parse and execute the command
      Display the resulting image

Which works "mostly ok" -- but when I do img.display and it
opens a new window... the new window (naturally?) has the
focus -- I would say "steals" the focus from iTerm.

Thinking about this, I suppose it relates more to the window
manager (and maybe ImageMagick and the OS) than to Ruby...

Having said that, I wonder if there is a solution to this, other than
constantly re-clicking in my original terminal window?

Thanks,
Hal
