None Electrons below 1keV

Hello,
   I am using  geant4-10-02-patch-02 on Ubuntu.

I hope to track electrons down to ~10eV (or even lower). I am using parts of the microelectronics example in association with example B2a (for a sensitive detector). I find that the hits are never below 1 keV. I came across this website which suggests a possible causes and solutions:

https://twiki.cern.ch/twiki/bin/view/Geant4/LoweAtomicDeexcitation

However, the suggested options such as putting this line:
 G4ProductionCutsTable::GetProductionCutsTable()->SetEnergyRange(250*eV, 1*GeV);

in the SetCuts() method of the PhysicsList did not solve the problem.

Also this UI command did not solve it: /process/em/lowestElectronEnergy 10 eV

Using this UI command /cuts/setLowEdge 250 eV

I get the following output: illegal application state -- command refused

Does anyone have any further suggestions ?

Thanks Chris
