LOL

I had just done the same before reading your latest post!

After a while looking to your vi, i wonder what is the purpose of that vi, then i decided to remove its, and check the results. It works well!

However, what really amaze me is the express vi, it's so convenient! However, it will takes more time and more demos until i finally get the point!
