Modifier keys should not have caused the input control to grab focus. Also, only the default input control, if any, has any business grabbing focus.

This issue has been resolved.
If you hold the shift key while playing a game, the focus shifts between interface elements. This is not desired, because it makes games which require the player to hold the shift key unplayable.
Which elements does the focus shift from/to?
That makes sense. I have to do some work on the input control anyway, and when I get to that I can incorporate a fix to avoid switching focus on modifier keys.
