Hi, Anna,

Yes, this was reported once before and has been reported to R&D for a future AR release.

For now, although the error may be a little disconcerting, we find that the customer actually is created and can be used in the invoice you are creating and subsequent invoices. I find that I am returned the invoice and can then use the Finder button to select the new customer, or just type the new customer's code into the field.

Thank you for reporting this issue.
