I think something's wrong with the maintenance release 7.0.5 PE The scrolling of grids or listboxes is not functioning any more on ipad (either safari or chrome) having iOS version 8.1.3+. Scrollbar is visible but scrolling is not possible. Trying a previous ZK version (7.0.3) behaves OK although it does not display any scrollbar.

Also, i have noticed that this example from the ZK web site is not working on ipad anymore. Maybe it is related somehow?
