I use the following for auto check entry in a workbook using XL2000:

Private Sub Worksheet_Change(ByVal Target As Range)
Application.ScreenUpdating = False
If Target.Count 1 Then Exit Sub
If Target.Column = 5 And Target.Value 1 Then
MyChks = Mid(Target.Formula, 2)
Range("I3").End(xlDown).Offset(1, 2).Value = "Food City"
If Not Target.HasFormula Then
Range("I3").End(xlDown).Offset(0, 4).Value = Target.Value
GoTo OneCheck
End If
v1 = Split(MyChks, "-"): v2 = Split(MyChks, "+")
If InStr(MyChks, "-") 0 And InStr(MyChks, ")+") = 0 Then
Check1 = v1(LBound(v1))
Range("I3").End(xlDown).Offset(0, 4).Value = Check1
GoTo OneCheck
End If
If InStr(MyChks, "+") 0 And InStr(MyChks, "-") = 0 Then
Check1 = v2(LBound(v2))
Check2 = v2(UBound(v2))
GoTo TwoChecks
End If
If InStr(MyChks, "+") 0 And InStr(MyChks, "-") 0 Then
Check1 = v1(LBound(v1))
Check2 = v2(UBound(v2))
TwoChecks:
Application.ScreenUpdating = True
Range("I3").End(xlDown).Offset(0, 4).Value = Check1
Range("I3").End(xlDown).Offset(1, 4).Value = Check2
Range("I3").End(xlDown).Offset(1, 2).Value = "Food City"
Range("I3").End(xlDown).Offset(0, 2).Select
If MsgBox("Was 2nd Check to Food City?", vbQuestion + vbYesNo, "Payee") =
vbNo Then
ActiveCell.Value = InputBox("Enter New Payee", "New Payee")
End If
OneCheck:
MsgBox "Check for $" & Range("I3").End(xlDown).Offset(0, 4).Value & _
" was #" & Range("I3").End(xlDown).Offset(0, 1).Value
ActiveSheet.Columns(1).Find(Format(CLng(Date), "d")).Offset(1, 1).Select
End If
End If
If Intersect(Target, Range("K5:K34")) Is Nothing Then Exit Sub
On Error GoTo Quit
Target.Offset(0, 2).Select
If Not IsEmpty(Target) And Target.Value 1 Then
Application.EnableEvents = False
Target.Offset(0, -2).Value = Date
Target.Offset(0, -1).Value = Application.WorksheetFunction.Max(Range
("J:J")) + 1
End If
Quit:
Application.EnableEvents = True
Application.ScreenUpdating = True
End Sub

I just discovered today that if I attempt any Copy/Paste operation using
the right-click context sensitive menu anywhere on the sheet, Excel
freezes and I have to close Excel to recover. I can't even close the
sheet. I exported then removed the code as a test, and no lockup. This
doesn't happen in other workbooks. Nor does it happen if I use the
keyboard's Ctrl+C/Ctrl+V combo or the main Menu's Edit Copy/Edit Paste
with the code in place. It occurs under Win2000 or WinXP on different
systems with different mice.

Can anyone spot anything that might trigger this behavior?
