Stuart, we're certainly sorry you experienced a problem. Hopefully, you're all set now.

As for emailing, this really never even crossed our minds. For most customers, this information would be either redundant, not useful in the first place, or just ignored. It would be a huge waste of time for nearly everyone. Does Apple email you when an issue is discovered? I've certainly never received such an email. Email's just not a vector that's generally used to inform users of bug fixes, by anyone.

We issue updates as quickly as possible, and we post info here for all to read. We also do our best to make it as easy as possible to update our software, which can be done right in the app. Just as with Mac OS X, it's best to always be running the very latest versions, of everything.
