Subject: Fix display update during Edit Book
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=2a1e296dac2afd76b0661e82ca5da911eef20697;p=xboard.git

Fix display update during Edit Book

When moves were deleted from the book, this was only shown after
quitting and restarting XBoard, because the stream that was used for
reading the book was a different one as the stream writing it.
