Since we changed to Acad 2004 the preview image (thumbnail) of the drawings disapears every time we use one of our custom routines that opens, modifies, and saves them. Is there a way of saving the preview image and put it back once the rountine is done? If the drawing is open and modified normaly with autocad there is no problem, but when we use a custom rountine VBA we loose it. Any suggestions will greatly appreciated.
