[news.eclipse.platform.swt] Re: keylistener doesn't work

[Brad Reynolds <bradleyjames@xxxxxxxxx>]

I'm just guessing here but it sounds like the second shell isn't 
receiving key events because one of it's children has focus.  These 
don't bubble up to the shell level.  Your main shell receives the events 
because it has no children and is the current focused control.  Just a 
guess, a snippet might help if that's not it.
