P40 Yoga Trackpoint not working after being docked

[cpfuller]

I have a P40 Yoga that I use with a OneLink+ Dock. The trackpoint doesn't work the first time the machine is booted after being undocked. The mouse pointer is available on the login screen but as soon as the desktop loads there is no mouse arrow and the trackpoint doesn't work. I restart the machine and everything works normally. If anybody has this problem or a solution please let me know. I have done a complete reinstall of Windows 10 and the problem still exist.

Thanks
Charles
