Subject: Fix deselection of greyed-out variant button (WB)
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=e5c6d13c4b6b683419f22274f9926cbee67d68f0;p=xboard.git

Fix deselection of greyed-out variant button (WB)

In Windows a disabled radiobutton refuses to deselect when you select
another (enabled) button from the group. There are then 2 buttons
checked, and the code to readout the buttons took the first one. Now it
is changed to take the first enabled one.
