Can't Copy Data between Workbooks

Neil has Excel installed on several PCs in his office. On most of these he can copy data from one workbook to another workbook with no problems. On one of the PCs, although he can copy data from one worksheet to another worksheet in the same workbook, Neil cannot copy data to a different workbook.

More than likely this has to do with how the two workbooks are opened on the problem machine. If you open the workbooks in two different instances of Excel, then copying and pasting between instances is not the same as when the workbooks are opened in the same instance. If you open the two workbooks in different instances of Excel, then when you go to paste information into the target workbook, you get the results of whatever formulas you are copying instead of the original formulas. (This is just one example; there are other pasting differences as well.)

The solution is to make sure that the workbooks are opened in the same instance of Excel. The easiest way to do this is to make sure that once the first workbook is open, you open the second workbook by using the Open dialog box within Excel. If you, instead, use the Windows Start menu or a Desktop icon to open the second workbook, you are opening a second instance of the program.

If this doesn't solve the problem for you, then you should make sure that there is no macro running in the target workbook or worksheet when it is activated. Look for code in the ThisWorkbook module and any other worksheet module in the target workbook's VBA project. If you do find a macro there, then it could be that the macro is altering what is in the Clipboard or clearing it out entirely. You'll need to do some detective work to figure out if this is the case.
