I believe the credit goes to Dr. Benway, although I could not find the orig. post, here are the instructions:
open notepad, paste the following:
#################
## file begins here
# Haptek Logging Control File
#
# c:HapLogCtrl.txt
#
# This file must be in c: and named "HapLogCtrl.txt".
# Otherwise it is ignored.
#
#################
debugger= y
#################
# file ends here
##
#################
Save as HapLogCtrl.txt (exactly as named) in yor C: directory.
Then when you open Hal, you will get a console window. Drag your haps, and other stuff into it to see changes in the Hal window.
