[DRG]

My guess is win7 has a record somewhere of that previous set up and keeps going back to it. As Andy says the game has no memory of the task bar position. None, zip, nada and given , as you say, the game worked fine before we know it can work so after you have tried everything else try what I suggested as plan B ( assuming you don't have secure PBEM going on ...) and perhaps that will clear whatever win7 is doing

I will also make a note to rewrite the warning regarding task bar position.
