Cannot view php-nuke pages in Dreamweaver using design mode

I've setup a complete webserver on my Windows box so that I can begin creating PHP-nuke sites, but I'm having a problem in that DreamWeaver does't show the view of the page or site when in design mode. This occurs despite the fact that if I select 'preview in browser' and it shows up fine. In other words, the phpnuke, mysql, apache and php are all setup correctly and I'm able to go to the site just fine manually and via dreamweavers preview option but it never shows up in the dreamweaver preview area.

Can someone tell me why this is occurring or tell me how I can fix the issue so that a phpnuke site is viewable via the design view?? I'm at a loss and figured there has to be some of you who use dreamweaver and also produce php-nuke stuff, if not, please forgive the post.

Any and all help would be appreciated!

I dont use Dreamweaver much, but I believe you need to configure dreamweaver to use php/mysql, it needs a test server in order to function
