Single click focus, double click bring to front

You might want to try XMouse

Take a look at all the options and settings, maybe there is a combination that will work for you.

I use it mainly to make my middle single click 'browser refresh' along with (optionally) left click 'browser forward' and right click 'browser back'.
I have these settings in what is called "Layers" that can be switched from default to at least 5 more layers with different mouse click settings that can be changed from the tray.

NOTE: If you make a mistake in your mouse button configuration, you can disable X-Mouse
Button Control by right clicking the icon in the system tray and selecting Disable from the
menu. You can also, if configured, use the scroll lock key or a global hotkey.

very important!

and it's easier to fix if you set the tray icon to always visible
I have lost my default left click function in a "layer" setting and forgot about that note.
