For larger customer names (possibly 15 char or greater), when the "Copy to Bill To" feature is used (or when the name is manually entered in the Bill To section), it seems the name gets cutoff on the left (almost like the field is being right justified), and you can no longer see the name properly. If you use the Home key on the field, the data is left justified again.
Once the focus is moved to another field and back, the same problem persists. This happens in Standard Mode, and on several different client installations, including the Demo DB's.
