Definitely think it is soley V4.0 that is the root cause of the issues, and yes the mentioned issues can be very unpredictable and random. Getting the same responses from users on the US forums, though always hard to tell how many are affected out the total ownership pool.
Clegy, I understand your predicament, and it is an issue that can only be resolved through XP alone vs you endlessly swapping out gear to try and sort things. I think the fact that no offical update with bug fixes has yet been released tells you the story that they are still having some issues or are still testing. Whilst the issues are an inconvenience, they don't really affect my detecting activities too much - probably lucky that our detectors even have the capability to be updated online, imagine if you had to send it back to the factory every time something went amiss.
Rocket, maybe try going back to 3.2 and use the pinpointer in non-wireless mode till things are sorted with an official update if it is too much of a pain. I ended up going back to using the HF coil with with the Garrett Carrot or MI-6 in non wireless mode till things are sorted, especially when there is the possibility of unknowingly walking straight over good targets due to the coil dropping out.
