Running GW14.2.2 127577
If I go into Address Book, right click on any address book, click Sharing, then click on the address book to find a name in the GW system address book, click OK - it doesn't appear in the share list.
If I'm in the main GW window, right click on one of my address book and do the same thing as above, it works.

Is this a bug or am I just special? I've been able to recreate this on different workstations as well.
