1) Is there any way of changing the serial number on an installed copy? We bought a legal copy for someone that "borrowed" someone else's copy. I installed 4.1b, since the version we received was 4.1a, but of course the "bad" serial number still shows. I'd really like to avoid reinstalling it from scratch since he already has data files. 2) Can both the address book and the calendar be shared on a network? 3) Does anything special have to be done to put them on the network? 4) Will DTS remember where they are on the network each time the PC is booted or do we have to enter the file name each time? Thanks, Gary Schulze
