I switched to Firefox and then Chrome, because IE got so that it was shutting down every 3 or 4 minutes. I've had the problem before but this go-round was much worse. My percentage went down into the low 80s. I'm nowhere near a 100%er but I'm usually around 94%.
I knew I had the problem, but I never knew that it was actually only a problem with this site. How could I not have known that? Anyway, I've just upgraded my computer and it's speeding along. Any problems with my score, are all me and not the browser.
