"You must restart your computer to apply these changes" on each dock/undock

[AnthonyB]

Hi,

Running Win8 x64 and connecting to a Toshiba Dynadock U (the older USB 2.0 based one) and using the 7.2M0 drivers.

Every time I resume from sleep after docking or undocking I get a dialog:

You must restart your computer to apply these changes
Before restarting, save any open files and close all programs
Restart Now Restart Later

(screenshot attached)

I've had this behaviour on multiple laptops; most recently my Lenovo X1 Carbon.

Any ideas on why the drivers are throwing this dialog?
