I updated to the latest version of the standalone viewer (1.8) and it still doesn't work.

Seem's like I missed some bugs with the second thing you mentioned. Can't promise that I'll be able to make another update soon, but I'll fix it with the next one (for real this time).
Thanks again for reporting it 🙂
