Vista - dressup challenge game

I play this game on the internet & you can post comments to other people
about their makeovers and give out kudos and do a community pick on their
designs. My problem is that when I go to comment my page just scrolls back to
the top of the page. So I'm unable to talk to other people or do the other
stuff. The only thing I can do is design outfits & vote on the challenges.
They say it is something to do with the security settings on my computer. I
have windows vista on my computer. I need to know what I can do to fix this
problem so I can play full version of the game. Can anyone explain what I can
do?
