OK, I solved the book problem, the weirdness in the Edit Position
click-click moving (the patch that makes a double-click on a piece start
a copy operation rather than a move had broken it, because it also took
mouse-button release events into account when timing for a
double-click), and the problems when starting from a position file
(LoadGame() was copying the start position directly from a board not
directly initialized when reading the position file, instead of using
InitPosition).
I decided to drop the <Return> = 'OK' in GTK dialogs, as I could not get
it to work satisfactory in spin controls. Besides, it is in the GTK
front end, and could interfere with the GTK3 stuff.
That leaves the highlight problem in the Engine Output window for PV
walking, about which I am completely clueless. Does anyone else have
this problem?
And I am still thinking on whether I should do something for Tamerlane
Chess.
H.G.
