I will double check the software, I "think" it is Version 11 but will make certain.
I never even thought about the cylinder maybe going haywire.

The little bracket that gets bent over, has a long finger that slides along the sensor housing, as it retracts, and there is a square cut-out in the side of housing. You can see the side of the sensor through the cut-out and it's got like a rifle scope crosshairs printed on the sensor. I'm assuming the long finger triggers something when it passes by the crosshair opening?
Just curious more than anything as to how it works.
Thanks for the help, I'll check the software.
