I have pe design 6 brother, when I open a file in Layout & editing, it takes up the hole page, how can I put it back to normal,I cannot push it small with the arrows, or move it around, hope you understand , thanks, wendy

I think you have hit the "full screen" button on your toolbar. On you internet toolbar at the top right, ( I run windows 8 ), on all the Microsoft programs, you will find the "tools" settings. Open tools and un check "full Screen".
Give this a try, or you can contact Brother online and they can help you with this issue.
Hope this helps,
Hugs, Bonnie
