I have a ti nspire cas (O.S. 2.1.0.631) that has a clickpad. I wanted to get gbc4nspire on it, so I installed ndless 2.0, using the 2.1.0 installer. When I tried running the gbc4nspire v.0.8, it crashed. When I tried using gbc4nspire_t, the left and right arrows (numbers 4 and 6) worked, but up and down (8 and 5) did not. Please help!!
