Not sure what the issue is, so I thought I would explain what happened and get feedback from others about whether it is compatibility, software, the keyboard or tablet... My wife has a Logitech bluetooth keyboard sold as an iPad accessory. She let me try it with my tablet. It found it fine and started using it and it generally worked for a while. Then something happened and shift didn't seem to work. Instead of ( I would get 9. And then all of a sudden the period started deleting the next character (not a backspace delete). The odd thing about that is that I had typed a period earlier in the same paragraph. It does have some funky Apple keys; I guess I could have hit one of those by mistake at some point. The weird thing is that all the alphanumeric keys still seemed to be fine.
