I want something that will lock and unlock via bluetooth. I've always got my phone on me at work, so if I go away from the laptop it should lose the bluetooth connection to the phone, which should cause it to lock. As and when I come back, the connection would be reestablished, and should in turn unlock the laptop.
Of course, that would probably also mean that my phone dies partway through the day due to lack of battery, but one problem at a time!
I'm not sure how to! :$
(it's windows 7, and too much has changed)
Cheers, Ant, found it!
Now to see if it gets set back to defaults on reboot!
