Same question was asked here:viewtopic.php?f=2&t=184893&sid=481d950fbdedbf4d8a87c5371c7f2a03#p631647
in july 2011 with one answer (general question) . Guess the answer was not sufficient ?
Another way is to remove the "Record" activity, which can be re-downloaded from sugarlabs.org as needed. ( Home page > listing display (top right) >remove "Record" > reselect icon display (circle with dot in upper right) ).
Assumes new user does not know of existence of Record Activity and how to download it.
You can always download the Record Activity to a USB drive (using PC and renaming file to removing any "zip" extension on the name) and it will be at hand for reloading the activity from the drive by clicking on the file in Journal.
