programs in physical hardware fail

[Angus]

So in order to have at least a working calculator I decided to re-type at least the user keys on the physical prime.
Without modified integer base handling on softkeys work is ugly in my eyes (please see petition on rpn changes, some way to autoexecute a returned string in rpn) plus some common simplifications and assignments I often use.

Now I am sitting here typing a medium sized program on the prime itself. What happens right now is that the comma key changes to a semi-colon key once I am in program editing! Is that working as intended or am I missing something??? How are you supposed to type in code - the comma is essential.
User Keyboard is switched off completely to avoid anything from that. I would really(!) like to avoid picking the colon from the char menu. Btw the dedicated semi-colon key is working as usual so I have two ways to type that char.
