The account look up feature is not very user friendly, unless I am doing something wrong. Version GP2016R2 16.00.0741
If you search by Description it only searches the start of the Description, you can't do a CONTAINS search.
The search by account number is just as bad. If I know my account is 000-52xx-00 and I search by Account or GL Number, by entering 000-52, it just lists all of the accounts.
Very frustrating when it used to work great.
