--- Comment #4 from Rich Rincebrain@gmail.com 2008-03-08 13:54:33 --- I really want to say it's something odd with 64-bit and Wine interaction, but I'm not going to claim that without further testing.
Could you try 0.9.51 or thereabouts? (This will eventually lead to a request to git bisect, but I'm trying to figure out if this is a new problem for you or if this has always been the case, and nobody with whatever configuration causes this has tried before.)
