For my implementation of Pentaho 7.1 CE, I need to get rid of this "Run in background" button: https://ibb.co/kQgsVo

But it does not allow me to do so. I was following https://jira.pentaho.com/browse/BISERVER-10883 but even if I deleted part:

          id: "runButton",
          text: this.i18n.prop('contextAction_runBackground'),
          handler: $.proxy(that.runInBackgroundHandler, that)
from file "~/pentaho-server/tomcat/webapps/pentaho/mantle/browser/js/browser.fileButtons.js" there was no change.

I have even tried to delete "~/pentaho-server/tomcat/work/Catalina/localhost/pentaho/" directory, but still no change.

Now I am not sure if I am editing wrong file, or failing at refreshing tomcat content. If anybody has a hint for me, i would really appreciate it. Thak you.
