Widen the field on the check form, change the font size of the RemitToName on the form, or abbreviate the vendor name/dba/remit to in Maintain Vendors. From what I recall, the default check form comes close to accommodating the 40 character vendor name, but most check forms are modified. I don't recall any clients with vendors that had names that were anything close to that 40 characters though.

The check form is the one associated with the bank account in Set Up Bank Accounts, or the one you choose in Print Checks. The report file name and location are going to be found in Set Up Business Forms. You will need Crystal Reports Designer to modify the RemitToName field on the form.
