I am running dual monitors powered by an Nvida Quadro 2000.
When I span the task-bar across both monitors, the solidworks icon is gone from the task bar.
this makes it quite difficult to switch back to solidworks when I am on another window. I have an office PC and a PC at home. Different videocars but they are both Nvidea quadro and it does it as well.
Image below, Solidworks is open but the icon dissapears when its in the background
