More theoretical fixes to the scroller. I didn't repro this on win, but I had a couple of cases on my psp - I suspect that the missing reset on the currentID counter was causing problems should the task list shrink after a duel. Also added a modulus calculation to make sure that we never go outside the bounds of the string vector.
