--- Comment #20 from Sebastian Lackner sebastian@fds-team.de --- I've updated the patch, please give it a try. GetThreadContext will now correctly return the values set in an earlier call. It doesn't contain caching on the client-side yet, but Hristo Venev is working on that. For now it will just always do a wineserver call.
