The preview is blank on most of my dwgs in the Select File dialog box. It has been happening over the past few months. If I open an older drawing, it previews fine. If I then save and close that drawing and try to open it again, the preview is blank. All of my newer drawings are blank. I would really like to get this functionality back!! Any help is appreciated. Thanks.
