Before one can enter SL, they have to read the terms of service and then click on the little square that says "I agree with the terms of service" in order to continue to SL. I tried to do this, but the box to click on and the "continue" button are fogged over and I am unable to click on them. Am i missing something? Am I supposed to click on something else before I can agree to the terms of service? Thanks for any help!
