Alvine, thanks. I got into the safe mode (I guess this was safe mode for Windows 8 -- who knows what it looks like) by pressing F8 during the boot process. Then I proceeded through the menus to do a Computer Refresh (it saves files but deletes added programs).
So, I get my cursor and keyboard back, but lose all the other work I've done in setting up new programs (applications????). My next call out will be to Norton to ask them why the 2013 Norton 360 doesn't work so well with Windows 8.
If anybody has any info on how to install Norton 360 over Windows so it works, please let me know.
