you need to use the software I will tell you can solve your problem.
it 's called "sou gou pin yin",find it and setup.
you can see a Panel list when you want to type Chinese by it.
you can find a small keyboard icon on the list,and kick right botton on it,and chose the No5 item,then you can see a small soft-keyboard.
you will see the all Chinese "yunmu" with tone marks.
good luck :D
