[Bug] "Enable mouse hover" makes other input devices unusable

[TristanCottam]

Hi, I seem to be having problems similar to #113, except it only happens occasionally, on certain or all keys, in no obviously recognizable patterns.

I have found the cause; I had enabled Enable mouse hover, which makes the interface practically unusable with the arrow keys or a gamepad, since the cursor always ends up on some title where it sometimes makes navigation impossible.

Mouse input and cursor position shouldn't have any effect when another input method is used.
