Embedded pictures in my Visio pages often "gets transparent" – after I save the document and re-open it, the picture goes blank, and I can only see its circumference (shape boundary) in the drawing.
When I 'point' the drawing in the file, I can still see the picture in the preview thumbnail, but not when I re-open it. Drives me nuts. I think it only happen with Jpeg, not with bmp. Any clues?
