Testing: keyboard anomalies...
Backspace function does not appear to work, so to delete text, i need to highlight and press some other key (e.g. spacebar period, etc.).
Also: return key does not work. This, combined with Backspace problem, makes it just to brutal to edit in the desktop (Mac) app... So i am editing this post via web interface -which seems to work perfectly as expected.
PS: issue resolved! (see next post)
