I've just installed 8.0c on top of 8.0b - no install problems. However, when I now select a file in the explorer window which includes a picture, e.g. mpg, jpg etc, and then click the Preview button, the Preview window stays black. If the file is mpg the frame counter in the Preview window ticks up and I hear the audio, but there's no picture. The Preview window is ok with video on the timeline.
Anyone have any ideas please?
