This script arrests the the newspaper blog I am reading at the time. Mouse and keys are immobilized The page does not scroll. The only option that I have found is to turn off the computer and start it up again. Firefox (or is it Google?) then lets me close the offended page/tab which disappears. Does not happen on three other newspaper blogs ! Sorry, I know about the internet only enough to read blogs, and am not a computer expert. Also, I am hard of hearing and cannot work with any phone. Looks like the problem I have described must be rather common as I try to cut away from the ads. Thanks for a written suggestion; here or through my email.
