I'd also love for it to work, but I'm also still getting the same problem. Full version from the Market updated to version 1.2.0. Tried removing HoneyBar completely, and cleared the App Cache / Superuser entry for Gesture Control, restarted the device and loaded it up again, all to no avail. When it stops working, I still get the toasts saying Show / Hide Bar, Back, Home etc so I don't think it's a problem with the gesture recognition itself, more with it processing the command. The "Manually toggle status bar on/off." button doesn't work either, nor does locking / unlocking the screen. So if it stops working with the status bar hidden, I have no option but to restart.
Some info about my device (all those having problems should post this in case it's a specific model / build / kernel?):
