Opera problem

[grafx1]

Today i started Opera 9 preview browser as usual, but when open sites as this site, i found Opera render it

incorrectly, there is a very long horizontal scroll bar at the bottom of the page (the pages are very wide)

i uninstall it and install Opera 8.5...but the same problem occur
