Hey folks, I am running into a real headache in Excel 2000, I am on Windows 2000 across a WINNT network. I am trying to copy and paste 24 columns of data with 500 rows of related data from one workbook to another. The file size of the target file is 1.26MB and the Source file is 2.27MB. I have a 384MB page file, and 260 MB of Ram. This is on a 1.4mz Pentium 4 client machine. I have installed service pack 2 for Office 2000 due to some related issues, and those have been resolved. Any suggestions guys???
