Great thnx

After looking in the right place lol
Confusion between 'Nautilus Actions Configuration' in the applications menu and standard 'File Browser' window

Should read (for Nautilus)
File Browser -->Edit -->Preferences -->Behavior, then, click on "Single click to open items".

yeaaaa

I have looked thru all the settings i can think of to single click icons in Gnome on Mint but i am unable to find any such setting.
Does anyone have a solution ??
