update: I think it was avast antivirus that was causing the clicknupload host to lag, because I disabled it, and then the navigation onsite was smooth/normal. Then I turned avast back on and it started lagging again. Unfortunately setting clicknupload as a url exclusion in avast did not work. Also noticed that the divx button is gone atm (for me, and the links I check anyways). So long as the files are playable with the flash player no matter, but when they are not then I will have to use daum potplayer, because vlc is terrible for me.
