RH crashes when changing values in firmware eeprom configuration

Hi,

I have the problem that Repetierhost crashes when I change the 2nd value in the config / firmware eeprom configuration. I tried this with Ubuntu and Mint on two different computers. It is possible to change exactly one value. Even after closing and reopening the window RH crashes while changing the next value. In Windows there is not such a problem.
Does anybody have an idea?
Thanks,
Svake
