Single click ? Double click ?

[Renaud OLGIATI (Ron)]

I have activated the "Single Click to open files" in both Thunar and Pcmanfm, and this works well.

But when I am in a prog that asks me where to open, or save, a file, opening a browsing window where I can choose the source or destination directory, there I have to double-click to open a directory.

Is there a way to make this single-click too, as per ancestral Unix/Linux practice ?
 
Cheers,
 
Ron.
