When I link into a client's network on site using the appleshare in chooser
I make the connection okay but I have to force quit the chooser to continue
working.

My computer occasionally locks up when I am linked to the network and the
only way I can restart it is by pressing the reset button on the back.

My Tibook had a major crash after two days plugging into their system and I
am concerned about possible damage to my computer.

Anybody have any ideas?
