Screen Designer and Multiple Languages
Some special rules apply if you use the Screen Designer in a multilingual environment.
If you use the Screen Designer to move components (fields, grids, group boxes) to a different tab, a message prompts you to review the affected tabs for every enabled language. The components display on the new tab in other languages in the same position as the current tab.
If you use the Screen Designer to move a custom component to another tab, the User Defined Tabs application displays the new tab for that component.
