I am typing text into the middle of a page and all the sudden, the text jumps
to the beginning of the document, as if I had hit cntrl -home Then I have to
scroll back
down to where I left off and continue typing the sentence. This happens
periodically as if I were inadvertently hitting some key or combination of
keys bringing the text back to the beginning of the document. Maybe I am but
I can't figure it out. I type fast. Have no patience.
I ran diagnostics and found no problem.
Thanks
