I like your design, the drop down navigation is great, I also like your donate buttons.
Your background seems to have a few blank white patches in it, there's a few spelling mistakes in there; and as you say when I look at in different resolution there's definitely something wrong, what editor if any are using then I might be able to assist you better?
Theres a big white space below the footer which I'snt doing anything you can put something in there or delete it, and also down the right hand column you have content boxes with nothing in them; you could put some website widgets in there such as a mini shout box or chatbox, picture of the week and lots more that's out there and available for use.
Im guessing you are using a free host, I would highly recommend you don't use one, lisa has a good article on free hosts.
