Problem: I just want to go back to using the Excel 2003 dialogs.
Strategy: Many groups in the ribbon contain a tiny icons called dialog launchers. You can click an icon to return to the old-style dialogs. This figure shows an example of a dialog launcher.
Take me back to the old dialog.
Additional Details: It is difficult to describe the dialog launcher icon. If you enlarge the icon, you can see that it looks like the top-left corner of a square with an arrow pointing down and to the right. I am sure there is some artistic rationale why these pixels mean "take me back to the old dialog that I know and love," but I can't figure it out.
