Post Views Plugin

http://lesterchan.net/wordpress/readme/wp-postviews.html

This plugin is working fine, except I would like to limit the number of times a person can count as a view (so people don’t refresh a hundred times to get a higher count) & it’s not counting the number of times a person clicks on the actual link to the website – it’s only counting how many times a person views the actual post…

Any solution to these two issues?

Thanks
