This happens a lot when loading large quantity of tweets and the only way to get the display back seems to be to drag the screen down.

It’s a shame Osfoora aren’t more responsive on Twitter or by email either.  A good product let down by poor customer attention?  The email went out a week or so ago and I’ve tweeted them a number of times.  Let’s hope they are busy making it better and aren’t too long before they give some focus to the customer.
