[Ifeffit] Artemis Crashed too often

Hello, I began to use the old version of Artemis in last September, and did not update till days ago. But after the installation, Artemis crashed very often. After running four fits, it will crash without any reasons (I did not close the graphics window). And when I restart the Artemis, sometimes it will give out information like: 'There seems to be a large number of abandoned project folders. This might be due to past program crashes or other past problems. I can clean these up at this time.' I am not sure if it happens to others. I work in Windows XP platform. Regards, Aria
