Dear CAS,
Yes,we've looked into a little bit but found no answers.... Question: do the adverts on the site keep reloading? Does this coincide with your keyboard disappearing?
I've just tried on a maemo & Android device and they both seem to work - so it may be a Safari issue. I will do some more testing this week and see what I can find.
For the time being, can you do a test for me please: could you download Opera Mobile from the App Store (it's free, don't worry!) and see if that works for The AnswerBank? Do you encounter the same problems?
Any further information you can supply would be great.
All the best,
Spare
