This is an extremely annoying bug. As others have mentioned you can set apps to open on on a different monitor. I open all apps on my primary monitor. See http://ubuntuforums.org/showpost.php?s=6c9b13a5e06988d3413925dd3937ce60&p=11852920&postcount=3
You can also drag windows with Workspace switcher. Simply click to show all workspaces and drag windows to appropriate monitor.
