I tried it and TurboTax does start up now! It's still pretty crash happy (e.g., "View Forms" kills it), but it's still impressive to watch it. Does anyone know how well TurboTax works with WINE on a real x86 machine? Does it work without a full windows installation? Perhaps more significantly, this apparently also was the bug that kept x86 abiword from working. Thanks, --david
