I have been using an XT with a 20mb hard drive and 640k memory for
many years without a problem, but lately, while using the WP50 and
WP51 software, the keyboard has frozen and I have had to reset the
computer, losing some text each time.  This has happened 4 times
in an hour today, on both the 5.0 and 5.1 versions.  The cursor
continues to blink, but nothing else happens, no matter what i
hit on the keyboard.  I have some theories, related to filling
up the hard disk (it has about 2.5mb free), or maybe the addition
of some new software to the hard disk (including and a fax program),
but would be interested in any suggestions or insight here.
I did not notice this problem using other programs, by the way,
but 70% of my computer use involves word perfect.
Thanks, GMS
