If you have your Insert or Open dialogues set to view files as Thumbnails and an image is corrupted, that might be a cause;
eg, select Insert from the Word menu, then Picture > From file, if the window that opens is set to show Thumbnails, then that might be the problem.
If so, hunting down the corrupted image may be difficult.
All of a sudden, every time I try to insert a picture into Word, an email, or copy a picture from the internet, that program shuts down with no error message. I have Windows XP SP2. The instant I open my picture file, it shuts the program down. This is a real pain! I'd be grateful for any suggestions.
