discovered can no longer edit Radio Buttons on existing forms. Forms have been in use for 3/4 years and are still working in HSQLDB versions but as cannot edit there unable to transition to Firebird. Clearly not a Firebird related problem. Need to edit as field name lengths (and Table name lengths) have to be truncated to suit 30 character limit in Firebird. Seems if a button is selected and data content inspected the next button says it has same data content!
