#2 keyboard's history panel unchanged

[Anonymous]

Steps:
1. Put ATM Simulator in service.
2. Type card's code
3. Press ENTER.
4. Enter pin
5. Out of service
6. In Service
7. The keyboard's history panel has the digits
entered before we putted the ATM Simulator out of
service; when the pin is entered (having n digits
already entered in the history panel) we will be able
only to type 4 - n digits, and what is more serious,
the ATM Simulator will allows us to access with the
previous entered pin.
