If I implied that, it was not my intention.
I use my iPad as a home theater remote. I can select controls for various components which show up as a sub screen.
The button lock out feature works on the main screen, but not on the sub screens. And not on my iPad.
A copy of my iPad is located at the bottom of this page:

The top section is also a sub screen. The only original screen buttons, or first layer, is on the right. The button "Ignore" feature works on those on my PC Touch Screen Viewer.
I think this feature is just something John hasn't gotten back to. I'm thinking it's not a complicated issue, just something he needs to take a look at.
