It’s better to reply as a reply, rather than in the comments; see Quinn’s Top Ten DevForums Tips for this and other titbits.

Thanks for that.

You only just filed this bug, so I’ve no news to share yet.

It looks like the CodeWeavers’ folks did a bunch of research into this. Do you know if they filed a bug about it?
