I assigned Ctrl-Shift-Z to the macro below. When I execute the macro via
Tools | Macro | Macros... | Run, everything works fine. But if I execute the
macro via the keyboard shortcut, the macro inexplicably stops right after
line 7. Has anyone else run into this problem and/or can explain why it
happens? Please note that "Rates.xls" is open prior to running the macro.

Any help would be greatly appreciated. Thanks.

3 - Application.Calculation = xlCalculationAutomatic
4 - fname = ActiveWorkbook.Name
5 - pname = ActiveWorkbook.FullName
6 - spath = Left(pname, Len(pname) - Len(fname))
7 - Workbooks.Open Filename:=spath & "Taxes.xls"
8 - Workbooks("Rates.xls").Activate
9 - ActiveSheet.Rows("1:5").Delete Shift:=xlUp
10 - ActiveSheet.Rows("2:2").Delete Shift:=xlUp
