  • Fixed message window width bug behavior because of DzHTMLText updates.
  • Fixed message text incorrect center alignment position when form at minimum size (issue #5).
  • Changed CenterButtons property to default false, because new Windows dialogs style have buttons aligned at right.

Please read the DzHTMLText Image Tag section to more info. Important: images won't be visible at design-time.

• 04/19/2020
