If you install Windows 10 RTM and Dynamics NAV 2015 development environment you will notice that the scrolling on the development environment with your mouse wheel does not work.
I was pointed to this by the NAV Yammer group and found it hard to believe since I’ve been testing with Windows 10 for a while.
This is a bug and will be fixed by Microsoft.
Fortunately Mibuso has the answer.
It seems to be a setting in Windows 10
Go To: Settings – Device – Mouse & Touchpad – Turn Off “Scroll inactive windows when I hover over them”
