The original Rich Text Editing control shipped with PowerBuilder was based on an OEM of a popular third party control at the time called HighEdit. By the time 10.5 came out though, that control was quite dated and no longer supported by the vendor. As a result, in 2006 Sybase replaced that control with an OEM of another popular third party control called TX Text Control. There are licensing issues with that control though. So with the release of PowerBuilder 2017 Appeon updated the control again, replacing the OEM of the TX Text Control with an OEM of the TE Edit Control.
