Here are some glitches with NL. The SAVE button doesn't actually save a listing unless you exit the program and do a backup. If the program crash....which it does OFTEN, all new listings and any changes made are lost. The only actually saved data is what's in the last backup. And unfortunately the only way to backup your new entries is to exit the program. There is no search function so if you've imported a lot of listings and want to change one you have to scroll through them all to find the one you want.
