Thanks for the reply,  Hal.  No luck... :-)

I started from scratch, reinstalling the reference file and choosing the 
correct picker.  I then exited lprof and looked at the RC file.  Here is what 
was there:


TARGET0=/home/paul/.lprof/target_refsR060101.txt
TARGET_DIR=/home/paul/.lprof/target_refs
TEMPLATE0=/home/paul/.lprof/templates/IT8_22.ITX
TEMPLATE_DIR=/home/paul/.lprof/templates

I then re-opened the target image and selected the corners.  Still got only 19 
columns :-(

I'm attaching the entire RC file, and I'll try out the CVS version.
