When entering debit/credit amounts, you have to wait for the $$-sign to populate in the field before you can enter the amount. This slows down the process of data entry and causes many typos to appear. (In the DB view, the $$-sign populates after you enter the amount.)
This trips me up in A/P invoice entry as well. (This doesnt happen with other financial software).
Yes, it does slow down the process because when you enter a number you have to enter the first number twice to get passed that $-sign it populates, hence the errors if you forget.
