We have a number of Excel users in our office who cannot copy and paste between Excel workbooks. They can copy and paste between worksheets. When you highlight the section to copy and then go to the new workbook both the paste and paste special are "grayed out". This is true whether you right-click the mouse, go to the edit menu, or use control keys. This occurs with any data type and the most simple workbooks. I have seen some suggestions here but none have worked for this particular problem. I have reset the menus and renamed the .xlb files and neither helps. You can open the clipboard and the paste will work, but there is no paste special option. Any help would be greatly appreciated. Thanks!
