Marvin,

I tried again, and I thought it had worked - after the wvdialconf
command, I had a list of S1 .... and on the same line the command line
prompt - but I could use the mouse, and clicked in another window. I
went back to the terminal window, pressed <RETURN>, and the screen froze
again. I waited maybe 30seconds before switching the laptop off.

Is there anything else to try?

Kind Regards,


Ian
