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'm sorry. I was very vague in the initial report. I am referring to the taskbar. The Display Fusion taskbar displays on the lock screen for roughly five seconds after the system has been locked. This issue occured several years ago and continued to display on the lock screen and the start menu could be activated by the win key which would open then display the Display Fusion taskbar. This is a security issue. I wasn't able to reproduce the win key issue on the lock screen.
