I have noticed inconsistent behavior while testing v1.4 of your screensaver with dual monitors. In the screen saver settings, if I select the Matrix screensaver and hit the Preview button, the screensaver displays properly on two monitors. If, however, I click on Settings and then hit the Preview button on that screen, the screensaver only shows up on one monitor.
