Subject: Give error popup when pairing engine fails
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=2519aecaae2982acac0884701ece95872937ef5f;p=xboard.git

Give error popup when pairing engine fails

An invalid pairing now produces an error popup to inform the user, so he
knows why the tourney stagnates.
