Hardware: Atom 330 w/ Ion HTPC; was on 8.0.2 and no problem w/ any previous versions w/ this.
After updated, it's got continuous button clicking itself so bad that the UI is no longer responsive or usable. I barely managed to move it a little bit then it won't do.
I then updated my RPi2 from 8.0.0 to also 8.2.4 and also connected the same USB receiver w/ the MCE remote (both Microsoft original products as a set), no problem at all. So it isn't the remote or the USB receiver.
So I don't know why that is. I rebooted the Atom 330 and it's still the same. In frustration, I wiped the box and put a Peppermint Linux 8 on it, no problem whatsoever. Strange.
