Subject: Fix WB New Variant dialog
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=165dd54f68ac49be0b50c3d2e1c5c054decdc5ac;p=xboard.git

Fix WB New Variant dialog

After selecting an engine-defined variant, all radio buttons would refer to
the already selected variant, and thus all appear active, but do nothing.
