I have two displays and using VS 2015 in multi-window mode (i.e., separate tabs on different screens). VS 2013 always showed only one icon on taskbar which was very comfortable but VS 2015 shows one icon per separate window. This drives me nuts!
I tried to find a setting to turn off this behavior but no results. Googling did not help much as well.
BTW, I am using Win Server 2008 R2.
Did somebody find how to fix this issue?
