I got no Widget other than Media player, This problem is an old problem. It has been and always been there. If your device is on more than 2 days it will be start to playing up. Hildon-home starts to spike up the use of CPU and RAM and at some point it crashed the device as well. I don't think you're the only one who never notice this symptom. Since 99.99% of all N900 users experienced it.
