Hi Stéphane,

Win32 windows send the messages WM_xBUTTONDBLCLK only if the window's class has 
the style CS_DBLCLKS.
NeL use this message to detect double clicks and send its messages.

If you use the default window created by the NeL opengl driver, it has not this 
style, so no double click are generated.
(See  nel/src/3d/driver/opengl/driver_opengl.cpp line 303 : wc.style   = 
CS_HREDRAW | CS_VREDRAW ;//| CS_DBLCLKS;  )

If you provide your own window to the driver, you can create it from a class 
with the CS_DBLCLKS style.

You can try the lowlevel mouse (Direct Input), double click is emulated by NeL 
so it should work all the time.
