When I start a new game using manual dice, all 72 dice images (in the window that shows the 36 possible rolls) are red. Thus there is no way for me to know if 1-2 means 1 for gnubg and 2 for me, or vice-versa. It seems that manual selection of dice at the very start of the game needs to be handled differently than manual selection later. It is already, in the sense that selecting a double (like 6-6) results in the re-appearance of that same roll-selection window.
