Many thanks mike -wsm, and Saab Dastard, you are right, I think what happened was there was an " AdBlock " upgrade that loaded that day but wasn't activated until the next start up. I noticed the window that appeared when I right clicked on the " ABP " icon was different. It does seem to be functioning better since.
A thought, is it possible to manually train it to block any video/Twitter type link , as sometimes script appears in the lower screen LH screen when it's slow loading a page?
Or is this not relevant ? Thank you.
