at the junction of the 10k and 22k R's is 10.83. On the other side of the 22k series R, ie directly on the Picaxe pin it is 10.60.
The reading at the 10K/22K junction is to be expected, but the reading on the PICAXE pin is not. The internal PICAXE diodes should have clamped the voltage to near +V and the 22K resistor prevents any damage in the course of that.
I would suspect that you either do not have a 22K fitted, you are using an input pin which does not have an internal diode fitted, an internal diode has 'expired' and gone open circuit, a strong enough power supply is not being used to hold the supply voltage at its own level.
On the 28X I am not aware of any digital input which does not have an internal diode fitted which would suggest one of the other causes.
With the same hardware configuration, same download cable, I am at a complete loss to understand how you would see different results with one version of the Programming Editor and another.
Added: What are the measurements on the pin when using 4.1.9 ?
