Rated 4 out of 5 stars
Sun's code is working but
there is a problem (minor)
Although the opened background windows is not in focus, it displays itself in focus in taskbar.
So to open the background windows u have to first click it to minimize then click again to open it in focus.
You can see it yourself
Fixed in version 1.5.1
Version 1.5.1 fixes the problem with opening background windows, and also fixes the taskbar button issue. All users of 1.5 are advised to upgrade to 1.5.1.
