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.
I use the tool ModernMix ( http://www.stardock.com/products/modernmix/ ) to run my windows 8 apps windowed.
Since windows 8.1 you can choose in the taskbar settings to show the app-icon on the taskbar. But the icon is always shown on the primary monitors taskbar.
Is there a solution to show the icon on whichever monitor the apps window is currently located?
I've just tested ModernMix here, and the app icon shows on the taskbar on the second monitor correctly for me. Could you send a debug log over? Here are the steps:
On the Troubleshooting tab, change the Logging drop-down to "Logging: Important Only"
Restart DisplayFusion
Move a windowed Metro app to the second monitor, note the time so we'll know where to check in the log file
Send us the DisplayFusion.log and DebugInfo.html files (can be found by clicking the Open Log button on the Troubleshooting tab)
