I'm currently wading through acres of debugging, which involves:
   REPEAT
       Small changes to the code,
       F6 'Build'
       F5 green 'Launch project' to test the result
       Stop the project using one of:
          - Menu in the project: File>close
          - Windows {*} gadget
          - SF's red 'Terminate' gadget
       Go back to the code
   UNTIL it works.

I am finding that, about half the time, my F6 'Build' attempts fail because, although my project appears to have closed, and to ended - for its Window has gone, the SF green F5 'Launch project' gadget has re-appeared - it has not.   Windows Task Manager reveals a malevolent zombie of my project executable still wandering aimlessly and uselessly about, preventing me from moving on, until I kill it off in Task Manager.  This is easy to do but it's a trifle slow, and therefore rather tedious.

Could any way be found in SF to close hidden remnants of project executables?
