I have made an Excel add-in, which pops up a window either by window.open
or Dialog API.
I just tested it in Excel for Mac: when the window is opened, it seems that we can NOT put the focus back to Excel or the add-in taskpane; we have to close the window before choosing Excel or the add-in taskpane.
Does anyone know if there is a way to enable switching focus between popup window and Excel?
