Debugger not stepping to next scene

Hello, noob here…

trying to locate a pesky variable that just refuses to remove itself, but the debugger in corona editor will not “run” beyond the main.lua file, which contains nothing more than:

> display.setStatusBar( display.HiddenStatusBar )
> local composer = require( “composer” )
> composer.isDebug = true
> composer.gotoScene( “welcome” )    <— stops here.

It does list breakpoints I set in other .lua files but no amount of pressing F11 or Shift+F11 will make it go forward.

Documentation on this seems to be a bit sparse… What am i missing here? TIA
