Subject: Fix a misrendering in Guess.
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=sgt-puzzles.git;a=commitdiff_plain;h=8889fafb07d47ba359ad071789f340df866a0321

Fix a misrendering in Guess.

When the cursor was visible, redrawing after undo-redo or label
toggling or resizing would draw background over the top of the
circular cursor.
