Glitches

I am experiencing this infuriating glitch that is probably the ipad's fault.. Not only can I not see what I type but sometimes I need to enter moves twice and when I don't realize this I loose five games on time and end up with a rating in the 800's. Oh well. I'll just have to play more games and check more frequently to bring to bring my rating back up so I can play games where the outcome isn't certain.
