Problem Crash Freeze: SYSTEM FREEZES WHEN YOU ENTER PROCESS SALE
SYSTEM FREEZES WHEN YOU ENTER PROCESS SALE
Most likely a error message is obstructed by another screen (ex. login screen). You can either go to the "Setup Wizard" & "General Setup" deactivate track employee activity login screen & enter again to view the message that is causing the freeze. Or can hold down enter key to try to access the cash register screen.
It also could be the error message "MPOS Has detected no records in your cash register data-MPOS will try to repair". This happens when you delete all invoices and sales receipts. hit the OK button you can then reactivate login screen.
