Hi, have 3 displays conf. Using Open Shell Menu + DF 9.5 on Win 10x64.
The main monotor start button click calls normal Open Shell, but the additional calls windows default that I can call with Win+Shift. Win key calls normal Open Shell menu, not clear.

UPD: Native windows taskbar working well and show right menu on "Start menu" click, DF taskbar is woerking like I told before. Start menu working well on Win key press in the both configuraions.

Even worse.
- Click on Start on seconrary display.
- Blue full screen menu opened (see the attach)
- Second click -> mene opend on primary display, closed, opened on the display where I clicked. Absolutelly chaotic. On the third - appeared on main, closed, appeared on third.
