admission: never got on the OZ bandwagon, was happy w/ Sharp rom 3.13
problem: The hardware switches on the sl-5500 sliding keyboard cover bounce quite a bit. You might push cancel once, and it close all your running programs. You hit home, it might blast through all the tabs several times before settling (rather like roulette). I've tried a few times to clean the contacts, but fear that the switches themselves might be the problem.
question: has switch debounce logic ever been added to OZ or Angstrom?
