I recently changed my computer, and now using VISTA instead of XP. One thing I noticed was the site does not register my votes anymore, as well as page views. I had the same problem using the work PC, but I thought it was just firewall type of protection for work place. Now even my own PC does it to me?! It has to be some set-up issue. Who's familiar with this problem ? Let me know ~!
Thanks!!!
