I see that 20 people have viewed your post, but you have not had a reply for 9 hours. That is unusual. I suggest you repost your question (with a bit more detail in the subject) in another forum. It looks like you have a computer problem, rather than a Pages problem. Go to:
and choose a forum that deals with your computer or operating system.
Mention which machine and operating system you are using.
