<p>If a button or other focusable element is inside a parent element that is invisible, it should not be possible to set the focus to the button. But it is in the current code, which explains why focus is so often invisible in WMC skin (for example).</p>

<p>To reproduce, in WMC skin go to guide, choose a program that isn't set to record, press enter, select Extended Scheduling. There will be no visible focus on the screen (the focus is on the "Do not record" button, which is inside a hidden grid).</p>
