Strange Exit game command issue

[Nicodemus]

I had launchbox and Bigbox setup for start+select on a xbox one controller to exit games and return to launchbox or Bigbox. I just moved my launchbox build to an external hard drive and now a strange thing happens, when I hit start+select to exit a game instead of exiting to the frontend the windows start menu opens over the game and a screenshot of the game screen is saved? 

Any Ideas?

After some trial and error testing, I have found the issue to be Steam running in the background. My best guess is the latest update of Steam must have changed something because when I exit Steam from running  I no longer have the issue. Short of never running steam I don't know what the fix could be?
