After install the adobe reader X, my safari 5.0.3 on windows does not work well,
it can't download any pdf file and only show a white page.
for example: I access the PDF file such as http://www.jreast.co.jp/map/pdf/map_tokyo.pdf cannot be displayed.
and when you resize the browser, the download bar will be displayed overlappedly.
It seems to be a bug.
