If you downloaded DisplayFusion 12.0 and are having issues with languages please re-download and re-install. We have repacked the release as 12.0c with the languages fixed.
Could you provide some more details on what you're looking to do? E.g. what are you wanting to happen when the monitor configuration change is detected?
i want to run 3 separate chrome windows in 3 display units and it works fine,but sometimes we switch off some display units. what i want is when we switch back display units that chrome windows should appear on separate 3 display units
Does each window have its own page unique page title? And do they stay on those pages? If so, you could save the layout as a Window Position Profile, then save the monitor configuration as a Monitor Profile, and assign the Window Position Profile to the Monitor Profile. (new record for using the word "profile" in the same paragraph )
