Not clear what you could do before and not anymore.
When you open a PC session, you have nothing yet
At this point: click on the Smath icon TaskBar ... bingo Smath.
From there, you can open any Smath work sheet from wherever
in the PC box as you have a single Smath session.
Now, if you want another Smath session, double click on the
Smath icon in the DeskTop ... not TaskBar.
You then have a 2nd Smath session identified page 1.
Do that as many times as you want independent Smath sessions.
Now, to reach those Smath sessions, hover on the Smath icon
on the TaskBar ... click on the one you want identified page 1.
From the Smath menu "Open", browse for the document you want
from wherever in the PC box. Do same for the other not yet opened.
Now, you have as many Smath sessions as desired for each of
your active screen for multiple consultations.
But, all that is BS & BK [Bull Shit & Book Keeping].
Open documents from a single Smath sessions ... open any number,
I know no limit. From your individual screen just consult the
one in cause. Just works great Win 7, SS 6179.
It can be done other wise.
