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.
You shouldn't have to re-install DisplayFusion. Could you check the Windows Task Manager to see if there are any processes called "nvsmartmaxapp" running?
No there is not. I know about the problem with those files so i already renamed them and the taskbars are working fine.
I went ahead and install beta 3 and no change. for Auto split but when I changed to 1x3 it worked. I know i tried both in beta 2 .
Just realized that in 1x3 the taskbars are not per monitor.
Did some more testing and found the results to be inconsistent sometimes mon split works while multimon taskbars does not and vice versa. It is like the problem with nvsmartmaxapp.
Sorry, was just waiting until I had time to test this out here. I've updated my machine to the latest NVIDIA drivers, and the maximize locking seems to work fine for me. Can you check the Task Manager > Processes tab to see if the nvsmartmaxapp.exe processes are running?
Aha! Could you try enabling the "Window Management" checkbox in the "Use these features with Split Monitors" section of the Monitor Configuration window? That should fix this up
