Show desktop button doesn't work

[Twisty]

Hello,

I've got a little problem when Wallpaper Engine is running, when i press Show Desktop button in my taskbar its working only on my primary monitor, not on my other one and its same thing if i do CTRL+D its not working to.

When i kill process of WallpaperEngine and i change my Windows Areo Themes, its working on all monitor.

I've try to sfc /scannow in command prompt, everything its fine.
I'm running on Windows 7 x64 Ultimate.
I was using Fences, uninstall it & reboot and still same problem.
If someone can help me with this issues.

Thanks

Do you mean that it does not minimize the windows on the screen? Which windows do you have open on the monitor?

[Twisty]

Yes its not minimize any Windows. Everything, explorer, chrome, Steam, Battle.net,.. its work only on m'y primary monitor

I think i've found something. When i quit DisplayFusion (program i use for a long time ago) its working great. Do you have an idea ?

And with DisplayFusion running, but without Wallpaper Engine it doesn't do this?

So it only happens when both applications are running?

I just found what was doing wrong.
My setting Taskbar Mode in DisplayFusion was : "All taskbars show relevant windows"
I have change this to : "Windows taskbar shows all windows, DisplayFusion shows relevant windows"

And now evrything works great. Do you know why there a conflict with this ?
Yes its always happen when both applications are running if i stop one of them its work great.

Maybe DisplayFusion gets mixed up with the windows of Wallpaper Engine? Although all of them are child windows of a standard Windows window (I hope that makes sense) so they should have ignored this window from the start and its children automatically.

I don't think so because all my others applications are not minimizing, when i press Show Desktop, my applications are staying at top but they are frozen, i can't interact with them since i maxmize it. The problem is just visual.

I have record a little video to show you the problem.

Thanks for your help

Thanks, yeah I can see the issue now. But honestly I have no clue - since I'm not messing with the show desktop button or anything. Are you clicking the button at 19 seconds or just hovering?

[Twisty]

Just hovering it, when I'm hovering it show all my desktop but when I click on it its ♥♥♥♥♥♥ :s

And when you use "Windows taskbar shows all windows" it works with both programs running?

I guess the other setting also changes the behavior of the show desktop button, so that it only remove the windows on that specific monitor?

[Twisty]

No to run both programs without issue i need to use "Windows taskbar shows all windows, DisplayFusion shows relevant windows"

No i'm using 4 monitor and i have this problem only on monitor 2,3,4, my primary doesn't have any problem with this.
