Subject: Fix one-click moving on up-click
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=fdde71b442baec96a0c2769f18fce4de49e34426;hp=0dc32b75bdb9cebc37c018c6d02f77aa30f440d0;p=xboard.git

Fix one-click moving on up-click

(First) up-clicks were not always ignored: in Edit-Game mode with
one-click moving enabled this could lead to a capture being made on
the down-click, and the recapture on the correspoding up-click.
This has now been corrected, and only the down-click of a first click
can lead to selecting a piece or a one-click move.
