Sure it will work fine without the cab because the real issue this thread solves is that Button 5 cannot be programmed to do anything other than Notes/Record. If you are happy with Button 5 doing Notes/Record then you've got no need for this cab file!

If button 5 was previously opening something else without this fix then I'm guessing AEButtonPlus had something to with it.

In any rate, glad you have it working the way you want it to work.
