This issue has been corrected in Claris Resolve 1.1
Claris Resolve will crash or lock up when saving a file as Excel 2.2 if the worksheet contains a function that includes more than 32 parameters. For example, the formula:
=Sum(A1,A2,A3,A4,A5,A6,A7,A8,A9,A10,A11,A12,A13,A14,A15,A16,A17,A18,A19,A20,A21,A22,A23,A24,A25,A26,A27,A28,A29,A30,A31,A32,A33,A34,A35)
