Have you tried enlarging the window when editing to see if
the text is there somewhere? Also try clicking in the editing
window and then hitting Ctrl A and Ctrl C then switch to Word or
Notepad and hit Ctrl V.
I am wondering if a style has been changed so that, for
example, you have a six inch left margin and just cannot see the
text.
I once needed a dropdown that was heavily indented and I saw
that effect.
