IF you have major problems defining the buttons in PTvncWM5 (eg. a single button press being allocated to two operations) then try over-writing the "buttons.dat" file on your PPC in the PTvncWM5 folder with the version from the original zip you downloaded (from Handango, PocketGear or wherever). This will hopefully set the buttons to a usable state, if you do this and still have problems then please contact support@parystec.demon.co.uk
