Missing Scroll Bar

I seem to be missing a horizontal scroll bar on this page, http://www.animefushigi.com/

If you make your browser window skinner, half the page will be cut off but there will be no scroll bar.

I believe the main content width should be 1024 px before the need of a scrollbar

because the wrapper div does not have a stable min-width(and for browser which not support min-width, such as ie6, there is a child div .wrapper has a stable width in this case, so it will be ok,too ),which should be setted.

e.g. //add css

#master_wrapper{min-width:1000px;}

It looks like overflow:hidden is used to clear floats in a couple of places. If you get rid of it on #master_wrapper then the horizontal scrollbar will return. However this will cause that element to collapse to a height of 0 and making this image disappear from your page. You can however rearrange your background images using the html for one of them to sort that issue out.
