Opening the Account Payment Arrangement form a second time may result in warning "Only one instance of the 'AccountPaymentArrangementAdd' form can be displayed at once"

After completing a Payment Arrangement for an Account, you are presented (if "Print Advice?" is checked on the first page) with a list of option to either View, Download or Email the Document.

Upon selecting one of these options, the form closed as expected.

However, if you re-opened the Payment Arrangement wizard again, a notification displaying a warning "Only one instance of the 'AccountPaymentArrangementAdd' form can be displayed at once" was displayed.

This did not prevent the form from being opened but was clearly incorrect.
