Recently I have had difficulty moving tiles to the right 2 columns of the scrabble board, particularly the far right. The tiles jump to other boxes in other columns or rows. This happens regardless of how I orient the iPad and I have tried turning the iPad in all directions. I have turned off iPad completely and then turned it on again, deleted and then attempted to re-install the game both on the iPad as well as on my laptop (at the suggestion of an Apple support technician) but to no avail. I never had any difficulty until yesterday. This is the only game in which I have difficulties. I have no problems with Words with Friends or any other word games. Suggestions?
