[vtkusers] Moving Parent Window

[Beau Sapach]

Hello everyone,

I have a series of images that I display in sequence to make a movie.  If I
click on or move the application window while the movie is playing it will
either freeze on the current frame or turn completely white.  How can I
avoid this?  Is it possible to keep the images updating while the parent
window is being moved?

I'm using Visual C++ for the application and VTK 4.2. It is an MFC dialog
application, and the dialog window (the only window) is the renderwindow's
parent.  Thanks!

Beau
