Hello all,<br>Recently I updated vtk from 5.0 to 5.4.2, and I found that the vtkTextActor cannot work properly anymore. The problem is that if I only add the vtkTextActor to the renderer, the text could be displayed, but then if I add some other vtkActors to the renderer, then the text simply disappear. Does anybody have the same problem? Any comments or suggestions are appreciated!<br>
