yeah, felt like a memory leak to me too. Mine would slow down then freeze or reboot. Hoping the update will help. I haven't really tested mine out too much yet, going quite gentle with it. I know I will get the sick feeling again if it freezes or reboots, so trying to make sure it plays nice for a day or two first before I experience disappointment LOL
Remember to report any issues after update as they are still fine tuning it I think.
