I have a form with customer information and a subform with customer detail. I scroll thru the customer info using the scroll keys at the bottom, entering detail for each customer. After about 3 or 4 customers, the detail fields stop accepting entry. I can tab thru the fields and click on the fields but characters will not appear in the box. I have updated Office 2000 with Service Packs 1 and 2. I have also recreated the same problem on a different computer. Any suggestions will be greatly appreciated.
