Could you try that out? I am not sure why we had those options.. Perhaps,
someone else who remembers can comment on this? (It is perhaps an x86
option in any case!)
It is worth a shot in the meantime...
Sorry I forgot, what exactly was the problem that you are facing? Is it a
performance problem or a functionality issue?
Thanks,
