If anybody to help me in here, I'm so happy and looks like to learn Vietnamese easier than now. My problem is something simple! Now let's explain for your reference.

1. OS environment : Windows 7 -32 bit
2. Vietnamese Keyboard : Unikey 4.0 RC
3. V. Font setting : Unicode + VNI
4. What for; look for dictionary through this site, Vdict or Vietgle by Lac Viet and writing exercise by both site online. So many " thanh điệu " make me tired really.. you know.
5. Problem : when I used to ON unikey and open writing tools like MS Word or Google Documents page, there is no problem in typing thanh điệu 1,3,5 6, but others 2,4,7,8 does not acted well. thanh điệu typing does not response..TTT
Maybe I thought this is happen by wrong font setting or other cause remain I do not imagine? Opening unikey introduction pages, I'm confusing there are so many font setting allowed. Which one is correct setting ?
