Hi, I've got a file server with a few excel files, not too big either, about 2 to 5mb. The guys in the lab keep getting this error when duplicating a sheet: "No more new fonts may be applied to this workbook" There are about 20 sheets inside this workbook with about 15 to 18 full charts and process data, and calculations. Why would this happen? I've seen excel files larger than this before.. Thanks, I appreciate a response or solution!
