Not sure, if I understood correctly, but it seemed somewhat related to using those zoom-in and zoom-out buttons - in later posts they tried some commands to wait for auto mode and then continue (sorry, I do not understand python code, so cannot explain. In other post they receive error messages in Axis about "cannot set TRAJ_SET_TELEOP_ENABLE in auto mode with interpreter idle", so it seems that there are some other workarounds to this, but not completely successful. -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Everyone hates slow websites.
