Hello Masa,

>I made a stupid question! Sorry.
No such thing. I hope my response didn't sound as though I thought it 
stupid....I didn't. I'm sure others were wondering, too. If you hadn't 
asked, you would _still_ be wondering. This way, all of us understand 
better, having had a nice clear explanation from Staz.
