Just bought the GOG version of this, and so far everything works okay after telling the Win10 compatibility wizard to do its thing. But for some reason the group selection movement isn't; it'll do the selection, but then only the character in the #1 slot moves; I've had to tell the others to move individually.

I'm going to try various compatibility options to see if any of them help, but I wonder if anyone else has seen this and happened to find a fix for it?

I'd need to install the game to check, but IIRC when the move-to target is terrain then all selected characters will move there; but if the target is an enemy then only one character will move.
