Missing Course/Bearing Line Through the VOR on 737

I am flying the PMDG 737NG-700 series (from the 600/700 only not from the 800/900 series download) under FS9. I enter the plane cold and dark and do a manual start up following the checklists. Flight works without issues other than I don't always get the green course line to display when I select a VOR on NAV1 and select the VOR toggle on the EFIS. If I enter the plane cold and dark and start up using Ctrl-E, and the course line appears and twisting the course knob gets the line to move around on the DU. I then tried a cold and dark manual start and after everything was up and running, I hit Ctrl-E again and the course line appears. My VOR is DME 1.2 from my position on the field.I'm wondering why the course line display only seems to appear when doing the Ctrl-E that is assigned to auto-start the engines? I think my checklist is fine as I can fly without incident and all seems to be working fine.Any thoughts on what I am doing wrong? Thanks.John
