I have Display Fusion v5.1.1 with Windows 7 Pro using 3 monitors. Monitor 2 gives me blinking lower right corner showing the desktop underneath until I move the cursor out of the window. Monitor 3 have problem updating with certain websites. I click of button to log in to my bank account and I nothing happens until I move the Firefox window to monitor 1. The website updated but the monitor is still stuck on the previous image. Sometimes I move the Firefox window on monitor 3 and it leaves a trail behind. Everything works fine on monitor 1.
