Funny TC, I came to the same conclusion and did just that.
By the way I have to thank you for many of your replies to some of my
messages, but could not give you a reply due to the fact that I was on
holiday (Still am, but have a small laptop that I carry with me, that I plug
to any phone). So thanks again for your help.
PS., even with your help, my Max is still a Max, but I'm proud of
it..........or not?????
I�m certainly proud of having friends like you.
Best regards, Charles ( [EMAIL PROTECTED] )
