Hi,
I was excited to see that you've improved the memory usage of the plugin after my webhost complained about the resource usage on my WP site. Unfortunately I didn't find any changes regarding this in the sourcecode, beside of that the advertising opens in a new window now.
Was that just another trick to show me the advertising, after I had to go to the plugin configuration page because EVERY WordPress admin page informed me in big red flashing colors that "All in One SEO Pack has new options"?
