Till reboots when a cashdrawer number is inserted

Very odd issue experienced recently where the POS appears to work fine.

That is until you try to enter a cash drawer number after logging into the POS.

This appeared to be an issue with the physical cash drawer itself.

By disabling the cash drawer in Till Configuration in BO (setting cash Drawer1 to None.

Then recreate till data for that till.

Select the correct till.
