Aspect ratio of Flash website


I have developed a couple of websites before in Flash, the problem is, the resolution of the site is good on my platform. i.e. 1024 x 800. However, when I get to view the site in 1366 x 788 the whole site looks sad. Badly oriented and sometimes I have to scroll through my page up and down - you know what I mean. :frowning:

Can anyone help me out here, as in how to solve the problem so that my site looks good, centre oriented, doesn’t matter at which resolution the user is viewing it.

If the procedure is complicated, feel free to guide me to tutorial links.
