Debugger's trace and break points suddenly not working with ADL

Hello,

At some point during my development cycle, when I debug my project (Actionscript Mobile with Starling and Feathers), trace and breakpoints stopped working.  I am not sure if I hit a keystroke combination that disabled it.

I have double checked my project to make sure I have debuggable swf compiled. I checked another project I have and the debugger is working fine.  Both projects are built with the same SDK versions.  I also compared project, module, build configs and they seem to be correct for the project giving me trouble.

Any idea where I can look to see what could be forcing my debugger not to work?  I am running  Mac OS X 10.10.5, and IntelliJ 2016.2.3
