Same story her (15" PB 5,2 1.25Ghz + pbbuttons + USB mouse). Not been
able to consistantly reproduce it.

This worked for me one time, but the other times the powerbook just
stayed completely 'frozen'. For the record, so far this has only
happened after deliberately putting the albook to sleep by pressing the
