Whithin 5 to 8 minutes of logging into SL, my typing starts to slow down, then the screen goes blue/black and i have the spinning wheel. Next I get a pop up that my video driver has successfully recovered, and then SL has a report of not responding. Usually it crashes and i get a runtime error from SL. and a memory address from the client as it has crashed. Sometimes i have several of these when i close one there is a second. This is the first occourance of this problem as 1.19 has never done this, and i can say that it never crashed on me as long as i have used it both on my desktop and notebook. I have not loaded 1.20 on my desktop but can if you need addational testing with 1.20, just let me know; I dont want to overload you. Good luck on this one.
