Subject: Put grab on sweep-selecting in Edit Position
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=1becd4475ad0305ed0ef30d3366117d8d061d9da;p=xboard.git

Put grab on sweep-selecting in Edit Position

A right down-click starting a sweep-selection event did not grab the
mouse events, so that an up-click outside the window would go
unnoticed, and the pointer motion stayed coupled to selecting the
piece until the next click. By returning 2 from the RightClick back-end
routine we request the grab.
