I've noticed that if I hover my mouse over either of my secondary monitor taskbars, the opacity of the taskbar is lost. I've set the taskbar opacity to 55% in the DisplayFusion Settings Taskbar section. When hovering my mouse in the taskbar, it appears that the opacity reverts to 100%. I do not see this type of action on my existing Windows 8.1 / DisplayFusion 7.2 system. There, the opacity remains unchanged.

My computer is configured with Windows 10 Enterprise, Clasic Shell (latest release) and DisplayFusion 7.3 (Beta 2)
