Build Problems (bug?)

I have been trying to build a small demo to test my games multiplayer function. I have disabled the Run in Background option but after I build the project I check and the setting are set back to "run in background". I have saved the scene and project and then closed unity and when I open it up the setting for running in background is disabled... It seems that only when I build the project does the run in background setting gets enabled without me doing so. Does anyone else have this problem or know what I am doing wrong?
