Problems with sidebar and pages

Hi! i’m new here and setting my blog i’ ve found some problems. The first one is related to the sidebar useing the defolt theme (kubrick). Starting to have many posts, the sidebar moves to the bottom and is not staying at the top like normaly. The second problem is related to the pages…When i create a new page, i write the text i want to see on it and than i save it.The problem is that in the blog i can see the link button to my page, but when i clikc on it nothing is happening and i can’t see the content of my page.
There is anybody how has found the same problems, or somebody that can help me to solve this!?
Thank you!
Bye
