Variables bound to the previous text wrapping option (wrap) will be automatically upgraded to the new overflow option introduced in Storyboard 5.3. Older runtime files (GAPP) will continue to work as expected but new files generated starting with 6.1 will only use the overflow option in the export. If wrapping was dynamically controlled as a variable then the model load into Designer will unbind this variable since the wrap property is no longer supported using the same variable parameters.
