Unfortunately I can't test my application under Vista since it uses 32-bit driver for copy protection and my Vista is 64 bit.
The application doesn't work with 32-bit oleaut32.dll copied from Vista, while it does work with 32-bit oleaut32.dll copied from XP.
Although it looks like the application is broken by newer oleaut32 bstr cache implementations, it works just fine with older versions. So, it should be feasible to make bstr cache in Wine compatible with those older versions.
