Thanks John for your report. Two small things :
Did you put the cursor at right (or left will give the same problem) of the locators before to run the macro ?
This sentence is critical “- place the cursor to the right of the right locator”.
If you have the cursor between the locators before to run the macro, it will always work regardless if it is run from the macro menu (or from a shortcut assignation) or from a control surface.
What kind of control surface are you using ? Is it using Eucon or Nuage protocols ? Or the midi remote protocol ?
I’m using MIDI remote protocol (JLCoopper MCS-3800 in native mode). I’m on Win7 32 bits.
I tried with Nuendo 5.5 and got the same problem.
