RE: [iPAQ] Decreasing frame rate on an h3600

Thanks for the info. Now the question (which I hate to ask, for I'm sure I
ought know it) is where can I get the hh6 patch? For that matter, is there
an open issues/patch repository somewhere? It seems I keep trying to fix
problems that have just been solved; sure would be nice to get ahead of
the curve and actually contribute solutions to problems that need them :)
