When I was trying to get WINE to behave I would sometime rename my
.wine to back it up and start over. That let me know if it was
something I screwed up in the configuration. Sometime copying to files
from one to the other worked, other times I had to reinstall. Drastic,
but it's a good last resort. And you can always move it back without
loosing anything.
