Network applet

I'm using Anton Maslovsky's Bluetooth PAN applet plugin to integrate with
the Qtopia network applet on a standard Sharp 3.10 ROM. The Bluetooth
Dialup applet works fine. The PAN applet correctly establishes a
connection - bnep0 is created with the correct IP address; I can ssh to my
Z from the laptop. Unfortunately, after a second, a dialog appears saying
"Connection Setup Error" - "No Connection detected. Check your TCP/IP
settings."

Clicking "OK" causes the connection to close - as does allowing the screen
saver to kick in! This is really annoying as the connection's fine!

I think the dialog is generated by the Network applet - Anton kindly
replied to an email about it but his suggestion didn't work. Does anyone
have any insight?

Setup:
MSI USB BT dongle on laptop running Win2k - static IP 192.168.70.1
Socket BT CF card rev G (yes I have this working!) on the Z
Bluez 2.3-2.4.18b
qtopia-bluetoothnetworkapplet 1.0.1
qtopia-pannetworkapplet 1.0.0
sudo 0.1
Settings on the Z - configure IP manually, IP address 192.168.70.2,
netmask 255.255.255.0, broadcast 192.168.70.255, gateway 192.168.70.1

/tmp/pan.log just shows a series of successful events

TIA,
Gareth
