Not very sharp w/pc's but i have hi-speed comcast & when i click onto something it is very slow to respond. I usually move the mouse around as it seems like the progress bar gets full & stays there unless i move the cursor sometimes against the scroll bar on the right of the screen as that seems to help. Sometimes i get a message or what the hell u call it at the top of the screen where it shows you what you are trying to click to & it says, windows internet explorer not responding. I cleaned cookies, temp files & history the best i could or know how to. HELP, REMEMBER I AM A DUMB ASS ABOUT P/C'S. Thank You
