HI Folks,
I have 2 displays in portrait-mode, both 1200x1920.
ghc 7.6.3
xmonad 0.11
xmobar 0.25

I've been reading several-years-old and even recent google results on this issue.
https://mail.haskell.org/pipermail/xmonad/2017-June/015266.html

xmobar --dock made the dock display on main (in display 1), though the window is still full-screen, not giving space for the bar.

Could any of you please describe to me how to:
1) instruct main window to give space for the bar? 
(other workspaces work fine, only ws2(display-1) does this.
2) display xmobar in both displays? (extra credit for separate bar contents -- not necessary)

 
Your help is most kindly appreciated!
