Having a hard time using Google?
My first advice before starting a new thread is: STFW first!
Well, first I would like to thank you for your help, secondly - I really don't like wasting my time searching through tens of pages from google results and reading sometimes pointless dabates and discussion of people who very often don't know what they are really talking about. I'd prefer to ask experts and if possible get if not answer at least a hint or direction where shall I start my search or what shall I try to read. Thats why I asked this question on this forum and used google.
As for STFW - absolutely no clue what it means;)
