Hi Ulrich,

Thanks for reporting this problem. This bug was in the daily build for a few days and was fixed two days ago, so if you get the latest build then showing the sequence should work. Sorry for the inconvenience.

No problem. I'm kind of embarrassed that such a basic bug was in there that long!
