Hi,

I just upgraded to Windows10 with a GTX-970 running a 3+1 monitor config and Display Fusion v7.1

The bottom 3 monitors = 3x 1920x1200 setup in Nvidia surround.
Adding 2x150 pixels for the bezels = 6060x1200 final surround resolution.

I split the surround monitor into 3 sections of 2020x1200 each
The left split has 100 pixels padding on the right side.
The middle split has 50 pixels padding on both sides.
The right split has 100 pixels padding on the left side.

When I click on the start button on the left, right and top monitors the start menu opens as expected.
When I click on the start button on the middle (primary) monitor, the start menu opens 50 pixels to the left of the start button so it's partly hidden behind the bezel. It seems to be ignoring the 50 pixel bezel padding but the start button and taskbar are properly positioned.

Other odd start button/taskbar behaviors observed.

1: Right click on start button only gives a popup menu for the middle/primary screen. This is NOT really an issue but the weird behavior on both side monitors IS.
right click start button on top screen is ignored.
right click start button on EITHER side screen results in the middle screen taskbar "jumping" to the clicked on screen overlapping its taskbar (but still no popup).
At that point, the middle/primary taskbar will follow the mouse, jumping from screen to screen until I move the mouse back to the middle screen and left click which seems to lock the taskbar back where it belongs.

2: Cannot change the width of the start menu.
When Display Fusion is running I cannot change the size of the start menu pinned icon area. I hover the mouse on it's edge and get the resizing arrow but when I try to left click and drag the menu just flickers and disappears. when I let go of the mouse button, the menu area reappears at the original size. I stopped Display Fusion, resized the start menu and then restarted Display Fusion as the workaround.

3: A few times Apps starting at random as already reported in other threads.

Thanks!

Huh...

Now that I've had time to play around with it, by removing all padding and reconfiguring the splits with unconfigured space between them that weird jumping issue (item "1" above) with the taskbar went away.

The only difference before/after is the 2 pics below.
