Your problem seems more realted to a memory leak and/or
some state not being correctly cleared (as you suggested).
My tow ones are systematic and happens eraly on. I tried with the single-thread exe and, when I go
back on the missed double decision the analysis panel shows some garbage
(in thw W(g) percentage). If I click on the copy button (text copy
of the analysis in the clipboard), it crashes. Single-thread exes
are here:
I also noticed something strange: when I experience
redraw issues (board and menus not refreshed, the cheque beside the player2 anme
(in the lower part of the screen) seems to appear at two or three slightly different
locations (it moves horizontally by a few pixels).
