[Bug 1590125] Re: Middle mouse (wheel-click) button stopped working after upgrade to 16.04

(easy enough :-))

No improvement - the middle button is still not recognized at all.

The requested output (no idea if the "invalid entry length" lines are

Invalid entry length (16). Fixed up to 11.
Invalid entry length (16). Fixed up to 11.
