You have to redraw the document window after calling certain API transactions, such as PlaceText and PlaceSymbol.
To redraw a document window:
· Use the Refresh(docwinID) transaction.
Choose the SetDocwinRefresh(docwinID, 1) transaction to make the active window ignore refresh requests while you perform a number of functions upon it. To find out whether a particular window accepts refresh requests, use GetDocwinRefresh.
