parts of WordPress can’t load properly

I am using the safari as my browser.
when i log on to my wordpress account, the dashboard is failed to load. but i am actually logged in.
when i try to post an entry, after i post ‘publish’ – it still say pages fail to load. but the post is published.
when i want to import links from blogrolling – it also says the pages fail to load – however this time it really doesn’t work.

at first i thought it should be the server’s problem or my connection spead is too slow. but it works perfectly on firefox…
does anyone encounter the same problem as i do?
and is there any solution to this problem?

many thanks!
