Can't edit 'doc' or 'rtf' document with Word or Wordpad!

[Don J]

I'm using Win-XP and Office XP. I'm having trouble opening either a 'doc'
file or a 'rtf' file and trying to edit it. I can keep hiting a key for a
long time, and nothing happens. I try to delete a highlighted passage.
Again nothing happens. Wordpad does the same thing. There is no problem
with a 'txt' file.

What is the problem? How do I deal with it?
