The "Read of Address" violation you received requires you to shut down AW2000 and restart your computer. You may have had a slight power surge or something. If it happens again after the restart, let me know.
As far as the "Remain on current record after duplicating" option. .....remember earlier today when you asked about the message you received when you were going to duplicate an Inventory Item abou the duplicated record will become the current record. And I told you that if you duplicated the Inventory Item that AW2000 would automatically move you to the new record. Well, checking that box will keep you on the old record instead of moving you to the new record automatically.
Some users check that option. Others do not. I use it sometimes and then other times, it is unchecked, depending on what I am doing.
