Hi there,

I have a context menu of

= Edit properties & delay, 900 & Close window & delay, 900 & Next item & Edit properties & delay, 900 & Close window & delay, 900 & Next item & Edit properties & delay, 900 & Close window

I want Opera to show a confirmation pop-up say 'COMPLETED' upon above Close window action is due.

What would be the command to add ?

Thank you very much.
Edmond.
