I've got Climatepredicition, Einstein, ProteinPredictor & SETI running, up 
until now I've had the first 3 suspended for a while. Now that all four are 
running, each with 25% resurces allocated, but Einstein won't share. Based 
on my preferences, BOINC is supposed to switch ever hour. Einstein has been 
running for 36 hours without a break.
