After moving to a Vista system, I have noticed that two changes have occurred. First, I can no longer choose 640, and I am limited to a maximum of 512. Also, at the end of the process of creating the video file, a window pops up indicating "Postprocessing output file...Please wait!" This message does not clear on it's own. The actual video file seems fine and I just delete the remaining temporary file in the directory. The progress bar does indicate "finished" underneath, but you cannot close the window without going into task manager to cancel the process.
