I see nothing sliding in here. Maybe you should check for virus/malware/adware etc.
CNET was my nr 1 site that I visited practically every day until recently. The main two things that is most discouraging is the infernal advertisement pop up that slides in from the left of the screen. I have to click on hide every time I enter the site.
the next thing is the softwares ability to get more stories at the end of the feature I click on more (plus sign) and the page just sits there and looks at me I have to restart the browser to make it work. what gives CNET ????
