If Excel is waiting for some user input, you can handle that - what you mentioned is the way to go.

The default handling is to wait some time and then show Server Busy Dialog.

You can show your own MsgBox and tell the user to switch to Excel.
Or you don't show any dialog, you just do a Beep:

From PAQ (10 pts): http://www.experts-exchange.com/jsp/qShow.jsp?ta=visualbasic&qid=20116886

' code to set focus to a cell
' it will Beep, instead of showing 'busy dialog'
'
Private Sub Command1_Click()

    Dim savtim As Long
    savtim = App.OleServerBusyTimeout
    Debug.Print "timeout=" & savtim
   
    ' temporary change the way your app handles OleServerBusy errors
    App.OleServerBusyTimeout = 200
    App.OleServerBusyRaiseError = True
    On Error GoTo eh
   
    objSheet.Cells(1, 1).Select ' error, if some excel dialog is opened
   
    AppActivate "Microsoft Excel"

ciao:
    App.OleServerBusyRaiseError = False
    App.OleServerBusyTimeout = savtim
    Exit Sub
   
eh:
    Beep
    Debug.Print "cannot select cell, error: " & Err.Description
    Resume ciao
End Sub

If someone thinks that that pending dialog can be automatically resolved - well, we normally do NOT do that, e.g. send Cancel - there are too many possible and unknown dialogs to handle that properly.

Thanks ameba, that would indeed mean that there is no other way of doing this than brute force or with user intervention?

Yes, user must check the message.
I don't know if you work(ed) with Win95, or with 20MB files with many pictures - I have seen messages when file is in 'danger'...
