For some reason the program refuses to allow more than 400 contacts in a single group. When breaching the limit it opens a single window for each name I attempt to move - this was great fun when I tried to move 50+ contacts into the main list.

Furthermore in my attempts to organize my contacts I've lost an additional dozen contacts for what seems to be no reason whatsoever. *sighs* Lucky I have a system back-up to fall back on even if my back-up isn't up to date.
