Dear friends, for some unknown reasons, some replies to my previous post has been deleted. The same occurred when I posted my message: I was unable to post anything and only thanks to Mike two of may attempts were published. I hope to be more lucky with the present post... Mike will ask Google to fix this problem, thought he was not so sure to receive sufficient attention. I would like to inform you that I have reactivated the "Leave a comment" option on my blog... so, if somebody wants to send me a message, please use that option (or write me an e-mail). Thanks to everybody. Ciao, PINO
