Adding Application.DisplayAlerts = False before invoking the other instance
may help.

| Hi,
|
| I'm developing a class which for a given filepath has to open the MS Excel
| and extend the context menu with a new item. When the item is clicked all
it
| has to do is to display a message box.
| Everything works fine. But if the message box is not confirmed (closed by
| the user) in a few seconds the "Microsoft Office Excel is waiting for
| another application to complete an OLE action" is fired by Excel.
|
| I want the customer to take his time to read the text and confirm (or not)
| the message box.
|
| How to handle this?
|
| Many thanks,
| Mircea
