Sluggish coding

While I appreciate the autofill feature when it comes to coding invoices, the problem I have involves the speed at which the software accepts the coding. If I do not select the coding from the pre-populated list, it wipes everything I have typed if I tab away from the field. This causes a major slow down in my productivity and sometimes even causes coding errors. It tends to waste time because I am having to type and re-type coding multiple times.
