Windows 7: Looking for bluetooth proximity application that unlocks your computer

I read about an application called Blue Proximity that supposedly could lock and unlock your computer based on the presence of a bluetooth device.

I took the leap and found 3 applications that would lock the computer when I turned bluetooth off on my phone, but none that would unlock it when I turned bluetooth back on on my phone.

Here are the ones that I tried:
1. Blue Proximity( free from Developer Dave <someone's> Web site)
2. btproxy 1.5 (sourceforge)
3. Rohos (commercial)

I'm running Windows 7, local(not domain) login, with latest updated and service packs.

It's sad that the unlock feature did not work, despite my spending hours researching and trying things, and after several reboots.


Maybe I've exhausted my options, as Google is not turning up any more applications for me to try.

However, if you know of one that you've tried and found that it works, please let me know so that I can try it!!
