Set Double-Click behavior on mouse?

[perfectreign]

I have been using a double-click action on the mouse for well over twenty years (Amiga, Mac, Wintendo, SunOS, Linux (KDE and Gnome).

Knoppix seems to want a single-click to open files and icons in the LXDE file manager.

I googled and tried to find the setting in preferences but cannot. I did see this very old thread - http://knoppix.net/forum/threads/4579-Enable-double-click-on-desktop-etc. - but the solution doesn't seem to be relevant any more.

Any help?

Try the following:
lxpanel>PCManFM>Edit>Preferences>General
Uncheck first box under 'Behavior' if you don't like single click.
