Mathematica Home Edition 8.0 banner ad

Mathematica Home Edition 8.0 shows a banner ad for itself across the top of every notebook. They changed the way they do this from 7.0 so my previous fix doesn't work. You can eliminate the banner ad temporarily using this expression:

SetOptions[$FrontEndSession,DockedCells->{}];

But restarting Mathematica will bring the banner back. Putting that expression in your FrontEnd/init.m or Kernel/init.m doesn't work. You can get rid of the banner permanently by editing SystemFiles/FrontEnd/TextResources/CommonFrontEndInit.tr and finding this expression:

SetOptions[$FrontEndSession,

DockedCells->FEPrivate`FrontEndResource["FEExpressions","HomeEditionBar"]

];

Delete that expression (or comment it out using (* and *)).
