 It certainly does not do that for most of us. You need to provide more
 information of what you actually do and what happens.

  1) are you in X or on a wscons console?
  2) can you switch virtual terminals after the lock? (with Ctrl-Alt-F1...F4)
  2) can you break into ddb when it locks up (Ctrl-Alt-Esc)? If that works
     type bt<ENTER> and take a phote
  3) does it happen for all files?

 ... probably more that I forgot

 Laptop not running X. Command line only.
 On login says: NetBSD/i386 (Amnesiac) (constty)

 less locks up computer when scrolling large text file, like
 /usr/src/UPDATING. When I begin to scroll down the file, less command locks
 up  the PC half way through reading the file. Keyboard becomes non
 responsive

 Thanks
