I have. What I found was that if you tell it to "Save as..." instead it will often succesfully save. If not... sorry. Something inside the file is corrupted probably, and if it's saved to a new file, it resets. (I'm TOTALLY guessing here!) Have you tried to send the file to Eovia tech support? Some of them prowl around here, (right charlie?) and maybe they have a better idea. Good luck!
