Logitech cordless 2.4 joystick problem

My friend has the joystick mentioned above. After instal and setup it appeared to be working fine.
After flying around a bit, switching the autopilot on, I realised that when the joystick does not recieve any inputs (throttle movement, stick or twist) it disconnect from the sensor. To reconnect you simply press a button on the stick but the problem is, when the jiysticj stops communicating it puts the throttle goes to full power and the trim settings go all crazy. After reconnecting, then switching autopilot off, the aircarft pulls 9g until you can get the trims back to normal.
I contacted tech support who new nothing of the problem but said the latest driver will fix it...but it didn`t. This joztick got a great review in PC pilot a year or so back so someone must have it - know of the problem - or knows how to fix it.
Thanks for any help.
