page not loading unless I resize browser window or highlight missing area

[anastasia]

I have a jsp page with an IE9 only issue. On page load, the page partially displays even though the user is led to believe the page is finished.
The only 3 ways I can get the rest of the page to show is if I hold down my mouse and drag my cursor across the area that is missing...resize the window by dragging it smaller or larger, OR moving the top of the developer toolbar up or down to make that part of the page smaller or larger.
