Hi Jerome,
I noticed this one a while back, and hadn't worried too much about it, but it cropped up a couple of times recently while I was doing some testing, so thought you might like to know...
If you load up a gamebox, move a couple of pieces, and then decide to load another scenario from the SAME gamebox, the Undo/Redo function is not re-set. Once the new scenario is loaded, and you click on the Redo Icon (now why would anyone do that? - I dunno, but I did ) then you get a weird white-out screen with outlined pieces displayed.
Regards, Bill.
