Sorry most likely swaping back to 1.0.1 it will not work due to registry differences between the wine versions. I am sorry to say 1.2 is not a offical wine version yet. It something ubuntu has done. Inside there is a 1.1.x something. The 1.1.x development line is not compatible with 1.0.1 line. Ubuntu could not be happy with labing the wine development line what it is. ie 1.1.x
