Task.Start() not working

Hi,

my first try on  the PC sdk and I just wanted to copy the simple program given in the RAB manual (I use IPython). 

Basically I have:

scanner = ABB.Robotics.Controllers.Discovery.NetworkScanner()
scanner.Scan()
controllers = scanner.Controllers
ci=controllers[0]

if ci.Availability==ABB.Robotics.Controllers.Availability.Available:
    #print "is available"
    c=ABB.Robotics.Controllers.ControllerFactory.CreateFrom(ci)
    c.Logon(ABB.Robotics.Controllers.UserInfo.DefaultUser)
try:
    if c.OperatingMode==ABB.Robotics.Controllers.ControllerOperatingMode.Auto:
        print "inside"
        print c.Rapid.GetTasks()
        tasks = c.Rapid.GetTasks()
        m=ABB.Robotics.Controllers.Mastership.Request(c.Rapid)
        print m
        tasks[0].Start()
        #c.Rapid.Start()
        m.Release()

now everything seems to work, taking mastership etc. but task[0].Start() has no effect. After trying around a bit I found that c.Rapid.Start() does the trick. 
My questuion, what is the difference between starting a task and controller.rapid start and why does starting the task not work?

Thanks,
tobias
