i have had all my w's, x's, y's, and z's disappearing. and one that goes before all the 1's. i realized once i added one, another would be deleted, but i hadn't noticed til every z medication wasn't coming out capitalized; but today, i deleted a few so i could add a few, and now all my y's and z's are gone and i haven't added a thing. this program is said to be "unlimited" like their competitors on the market. but, it's clearly not. when i figured this out, i emailed them. and 3 more times since--these are the only emails they won't respond too. they had me uninstall, reinstall--but that was before i figured out every time i added one, one at bottom automatically deleted. today, a week later without hearing back, i noticed i have 10-20 missing but by no means have i added any entries (since i know existing entries would be deleted).
