Well, in Fix32 you could (IIRC) copy view.exe and run it again.
I don't have iFix 3.5, only 4.x and you can't do that with workspace.exe.
However, just span the desktop across both monitors and design the pictures to fit only one monitor (size wise) and then you can have two open at once, a left one and a right one.
I'll second parky: Have one SCADA node and and an extra View nodes. Or a blind SCADA and two View's.
