Subject: Attempting to begin a drag from (i.e. just click on) the hint pegs
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/puzzles/commitdiff_plain/dbc6e45a10e0b77398198f06527959dc51b47020

Attempting to begin a drag from (i.e. just click on) the hint pegs
for a past guess caused strangeness up to and including segfault,
thanks to bad bounds checking. Well spotted John Sullivan.
