Hay guys, I recently run upon this feature, it is really neat. It didn't mess with my puter either. With this feature, when you hover your cursor over a thing or subject, a little blue box will appear, move the cursor to the blue box and a downsized box will appear with a new screen that you kan go to without clicking it on. It works good on topics here on the RCS, as you don't have to leave the original screen to follow the comments on a post.
