Start10 Menu buttom does not work on one monitor in multimon mode
I have a fully updated Start10 running on Win10 v1803, Build 17134.829
I have a Surface 2 Laptop which I use stand alone and with 2 different USB3 docking stations (work and home) that have 2 additional monitors. At work when I'm docked I have 2 HD monitors attached and I use one of my USB3 HD monitors as the main display. When I am in this configuration the Start10 menu button on the taskbar shows up on all 3 screens but on the Surface2 display it does not work. I click on it repeatedly and no Start10 menu. The other 2 displays from the dock have functional Start10 menu buttons includign the one display that is the main display. When the computer is in this state the Surface2 Start10 key remains inactive even when I undock and I cannot use the laptop and have to reboot it.
When I reboot it stand alone it works fine.
At home I have a different USB3 dock and a different alignment of 2 HD displays. In this configuration the same PC has no issue with the Start10 button on the Surface 2 but one possibly important difference is in this second docked configuration the Surface2 display is ALWAYS the Main display in the multimon unlike my work USB Dock multimon where the Surface2 display is NOT the main monitor.
Another interesting detail on the work moltimon that results in an inactive start10 key is that if I boot this config with the Surface 2 configured as the main display on my work docked setup it never seems to happen even if I change the main monitor away from the Surface2 after it has booted. If I DO boot in the Work USB3 Dock scneario with the surface NOT the mainmonitor the Start10 button NEVER works on the Surface 2 display.
