I have recently replaced my computers that run the lookout client. The old CPU's were Celerons, and worked fine. The new ones are AMD Athlon 64 dual core 5000+ processors running XP 32 bit OS (which was the same as before). I have seen some bulletins on NI's site about a patch for these, but it is not available. Lookout is running, but it can be sluggish and lock up at times. Any advisement would be appreciated.
