Need Help to solve problem with Word

I am having with Microsoft Word. After copy a whole
page from a website ( included text and graphic ), I paste
the copy on Microsoft WORD . However, I cannot paste
it 'cause
my computer (Microsoft Word) is hang. Checking Windows
Task Manager,I see the message :

" Document-Microsoft Word is not responding "

If I copy only text , I can paste it on Microsoft WORD
easily. This problem happens everytime when I copy a page
with text and graphics/pictures

Can anybody help me to solve the problem?

Thanks
