I've just connected an IC-BK10 to my macbook and while the majority of keys are working correctly, the right-hand shift key makes the curser jump up a line after input, while the arrow keys, once pressed, continue to push the curser to the start of the text box that I'm writing in. This makes the keyboard unusable and I can't see a way to change the setup to account for this.

Any assistance would be greatly appreciated.
