Ok ignore (above) it is not the reason it isn't getting drawn.

However. This seems to solve the problem.

Replace this line 715 TrackArtist.cpp

             if (min > 0) {
                botval = -((1-min)*mdBrange);
             }

             if (topval > botval && bot > top+10) {
                vruler->SetBounds(r.x, r.y+top+1, r.x + r.width, r.y + 
bot-1);
                vruler->SetOrientation(wxVERTICAL);
                vruler->SetRange(topval, botval);
                vruler->SetFormat(Ruler::LinearDBFormat);
                vruler->SetLabelEdges(true);
                vruler->SetLog(false);
             }
          }

With this

             if (min > 0) {
                botval = -((max-min)*mdBrange);
             }

             vruler->SetBounds(r.x, r.y+top+1, r.x + r.width, r.y + bot-1);
             vruler->SetOrientation(wxVERTICAL);
             vruler->SetRange(topval, botval);
          } else {
             vruler->SetBounds(0.0, 0.0, 0.0, 0.0); // A.C.H I couldn't 
find a way to just disable it?
          }
          vruler->SetFormat(Ruler::LinearDBFormat);
          vruler->SetLabelEdges(true);
          vruler->SetLog(false);
