On my X1 Carbon 5th gen (Windows 10), when changing 'Mouse Properties' => ThinkPad (tab) => TrackPoint => 'Middle Button Action' to be 'Use as middle click' (instead of 'Use for scrolling'), it works for a few minutes, but then, without me doing anything, reverts back to 'Use for scolling' automatically.
I tried this solution: https://forums.lenovo.com/t5/Windows-10/FIXED-Middle-Click-Functionality-Disabled-on-Windows-10-upgr... (namely: use regedit to change "TrackPointMode" from 00001214 to 00002214 under HKEY_USERS\S-1-5-21-<....numbers...>\SOFTWARE\Synaptics\SynTPEnh\UltraNavPS2). The effect was that, after a reboot, I manage to get the "Use as middle click" behaviour, but, then, again, only for a few minutes, after which it indepndently goes back "Use for scrolling".
Any idea how to make the "use as middle click" behaviour stick?
