The problem is that you have to know the handle of the window you want to hook your skinbox to...
...and when I'm talking about "handle" you should know that it is not the same each time the window is create.
...and when I'm talking about "window" you should know that it could be any kind of window; not only skinboxes or lsboxes. And that's really great :)

So, using RabidVWM, you can dynamically know the handle of almost any window... but not litestep windows. So I have no clue to know the handle of a litestep module...
