Confirmed. With "computer" in the crafty.rc I got this:
show book statistics
hash table memory = 48M bytes.
pawn hash table memory = 12M bytes.
EGTB cache memory = 2M bytes.
choose from book moves randomly (using weights.)
choose from 5 best moves.
4 piece tablebase files found
threshold set to 6 pawns.

What is not the expected behaviour IMHO.
Workaround:
After Winboard is started press "Alt+1" at the keyboard at enter "computer"
manually. Here I got the following result after doing so:
White(1): bk
White(1): computer
