Hello,

the following macro performs only if I set one or more breakpoints in it.
If I run the macro without breakpoints I get one error that says the Data
refresment is impossible owing to the protection of some cells or graphs.
The external data are contained in the sheets A, B and C only.

Sub UpdateAll()
Sheets("A").Select
ActiveSheet.Unprotect
Sheets("B").Select
ActiveSheet.Unprotect
Sheets("C").Select
ActiveSheet.Unprotect
ActiveWorkbook.RefreshAll
ActiveSheet.Protect DrawingObjects:=True, Contents:=True,
Scenarios:=True
Sheets("B").Select
ActiveSheet.Protect DrawingObjects:=True, Contents:=True,
Scenarios:=True
Sheets("A").Select
ActiveSheet.Protect DrawingObjects:=True, Contents:=True,
Scenarios:=True
End Sub
