Meantime, go to the Window menu in Expert view and click Restore Workspace.
Maybe I am looking at your question from another angle, but I do not see where Window Menu/Restore Workspace is going to help since you do not see that when you are in Full Screen where I believe you are (based on how I read your description).
If you were in the Premiere Elements 11 or 12 Expert workspace and got into the Full Screen view, then I see three possibilities to get back to the "normal" viewing
a. hit F11 key
b. hit the Esp key
c. at the bottom of the Full Screen viewing, bring up an option bar and click on the close button.
Please let us know if that works for you.
With regard to your second question
I need help geting my subject in motin to be croped smaller
Could you go into more detail on that? Are you referring to scaling and/or positioning or something else? Posting a screenshot may help, if a description does not capture what you seek.
