Why does Airlock lock the screen even though I'm near my computer?

If Airlock locks the screen when it shouldn't it's often a sign that the activation range is set too low. Because the perceived signal strength of your device can often be sporadic, you should set the activation range to be generously above the location of your iPhone on the radar screen.

A good method of finding the best activation range is to set it to the maximum and decrease it gradually until Airlock misbehaves, waiting five or ten minutes between each change. When Airlock starts locking the screen mistakenly, raise the activation range to last point where Airlock functioned correctly.

Additionally, you may find that Airlock performs better if you remove your iPhone from your pocket and place it on your desk, for example.
