I have a workbookwith 84 sheets. When I try to select (or activate) a range I
get runtime error 1004. In debugging the file, I find I can print the
individual cells (in a different workbook, wkFix), but cannot select the
range. Here's the relevant code:

With wkState.Sheets("NDX1")
For j = iCol1 To iCol2
wkFix.Sheets(1).Cells(j - iCol1 + 1, 13) = .Cells(jRow, j)
Next j

' I have no problem in printing

Range(.Cells(jRow, iCol1), .Cells(jRow, iCol2)).Select

'But the above line gives me the runtime error

End With

Can this have anything to do with the number of spreadsheets?

I'm running VBA 6.3, Excel 2003 SP1 with XP Pro

TIA,
Mike
