Safari Right Click menu problem after 10.5.5 update

I just now installed the 10.5.5 update on my Macbook pro. After the installation I see that the right click menu on safari is placed below the mouse cursor and not beside it.

I have attached the picture to depict this problem. After clicking a link on google news, you can see that the menu is way below the link.

Even when I click the dropdown bookmarks folder on the bookmarks menubar, the dropdown list is way down.

Has anyone noticed this problem? Is there a fix to it?

 

I just rebooted my laptop again. I don't see this problem now.
