>If I put the window in the middle, thus split on two monitors, I can scroll the grid on on the right monitor, but without moving the window (just using the mousewheel), I cannot scroll it on the left window.

>Walter,

I cannot reproduce this, works as expected on my machine. It's a Fujitsu Celsius H910 with two external monitor. One of the external monitors is connected to the VGA output, the second via a USB-to-HDMI converter. Win10 Pro 64-bit.
