If you don't mind, I'd have two requests:

1. Please, use meaningful subject. It will help people to read your posts
as well as search through the archives.

2. Please DO NOT send your posts in HTML (http://asciiribbon.org/). As 
you can see above, your post is completely unreadable as messed with 
XML/HTML entities.

Thank you!

Greetings
