Showposts pagination

Hi,

I’m using the is_home conditional tag to display 6 posts on a homepage and some additional intro content, then when it’s a standard archive page it relays on the wordpress setting which shows 15 posts in the blog. This all works prefectly aside from pagination.

When I’m on the homepage and select the 2nd page it shows posts as though the homepage showed 15 posts, so page 2 would start on post 16, so in fact there are 9 posts hidden as they’re not on the first page or second, I’ve tried offseting the posts by 6 on the second loop but this breaks future pagination.

Any suggestions on how this can be resolved ?
