Double clicking on a folder

How do you configure the lister so that every time I double click on a folder it dosen't open a new lister? :cry:

Thanks in advance

In the Opus File Types editor, All Folders type, Events tab there should be a dblclk (double-click) event that runs just go on its own.

That should be the default, though, so maybe there's more to this?

Is the above doesn't solve the problem, just to confirm, when you double-click a folder in an Opus lister it opens another Opus lister? You're not holding down shift or any other keys when clicking and it happens when double-clicking a folder in a normal location like C:?
