Older versions I know at least, such as V2 can have multiple windows open.

However, considering this can be resource draining on your computer, its not really recommended. And I don't know why you would need to.

I mean I can understand VOCALOID and Piapro Studio being open at the same time, but not the vocaloid software itself.
