+Summary: Document.RecalculateDocument has infinite loop
+
+When setting the text content of a TextBox via the Text property, an
+infinite loop can be triggered.
+Looking at trace output we see that SWF.Document.RecalculateDocument is
+calling SWF.Line.RecalculateLine for ever (even assigning text with only a
+few lines).
+(here is trace output - how sure how pasting it in will go...)
