Good Morning

Any advice on this would be appreciated please, I do not use pastel at all, but need to assist an accountant who does. She uses the tab key to navigate through the columns and says it has started going over columns which are supposed to require an entry before going on to the next column/line. Apparently it did not do this before. It seems to be mainly the 'cash code' which she is concerned about. Is this abnormal? Or is there perhaps a setting that needs to be done to make sure that an entry cannot be skipped? She is using pastel 2009

Kind Regards
