If I have two different windows of an application, let's say Chrome, open on the same non-primary monitor, the icons get grouped on the Display Fusion taskbar. But if neither of them are the active application, when I click on their group of icons on the Display Fusion taskbar, nothing happens. They stay in the background. On the Windows taskbar, I have to hover the cursor over the group and then click on the "preview" of the instance that I want, but Display Fusion does not offer "Previews" to choose from.

I've figured out a workaround to just disable app grouping on the DF taskbar, but it seems like there would be a better solution. Am I missing something, or is this just an issue that doesn't have a better solution yet?

The DF Taskbar does offer previews, do you have them disabled in the Taskbar section of settings?

Also, I have the Windows registry tweak enabled so left-click on a group brings up the first window, and continued clicking rotates through the group.

Still works in Windows 10...

I'm assuming you are referring to "Window Preview Style" in the Taskbar portion of Settings. I have "Windows default style" selected and it currently shows none. I've tried "Windows default style" as well and that also did nothing. See attached.

I restarted the computer and it seems to be working properly now. Thanks for the help.
