I have dual core and i can not upload because it says that climate has 90% of the core time when both cores run then i have two programs running! is there a patch for this? Thanks,Dave

Do you mean 'why does a single WU not use both cores to run'? If so, the answer is simply that there is no benefit to doing this - you get just as much done running two WUs at the same time as you would splitting a single WU across two cores. (this isn't true for every project, but to the best of my knowledge Milkyway doesn't stand to gain from only a little parallellization) Multithreading applications is also somewhat time consuming to setup, so it would be a big hassle for no gain.
