For years we have used bespoke forms for Open Invoice Customer Statements. We recently moved up to 8.1 (because of El Capitan). Very impressed, its nice and quick.
The file template held in hansa is my bespoke version, but when i ask for a statement I get a sort of default old version. I've deleted and re-pointed the form definition but to no effect, It still picks up the default. yet other bespoke forms like invoices and delivery notes still work perfectly.
