Even with ppAllExceptForEditFields set, I can easily move the text cursor outside of an edit field by using the up cursor movement which freely moves the text cursor to the previous line, and then I am outside of an edit field and then can click or cursor anywhere and the cursor goes there.
It sometimes does restrict the cursor, but moving the cursor to various points in the field can get it to move outside a field rather easily using the up cursor key.
