Add me to your new list then. TB starts up in ~1min. Sometimes it will just hang for a few minutes while updating emails/calendar. (Can't switch to its window) Sometimes it will take 10s+ to dismiss a meeting reminder. Sometimes the meeting reminder can't be dismissed. Sometimes it will get confused by filters working slowly and both beep for a new message and then immediately move it away.

There are bugs upstream for all of those. They're up there for years.
