Scroll wheel as middle mouse button.

[Staf Verhaegen]

I already reported this once before but got no reply so I'll try again.
I'm running the newest X version from setup (4.2.0-43) updated today.
I'm problems with using the scroll wheel as a middle mouse button in X.
The scroll messages of the wheel mouse are transferred OK to X. E.g in mozilla 
running under X I can scroll the window with the scroll wheel.
It's when I click the scroll that nothing happens in X.
I'm using Win2K SP3, and the mouse is configured with the Logitech MouseWare 
Control Center (Control Center V9.60.146, Mouse Driver V9.60).
I can assign different bindings to clicking the scroll wheel. I tried 
'Unassigned', 'Middle Button' and 'Double Click' but nothing of that made a 
difference.
I also ran X in fullscreen, as a window on the desktop or in -multiwindow but 
also this didn't make any difference.
I'm a long time UNIX user and the lack of a middle mouse button is a big 
handicap (for example in mozilla I use to open a link in a new tab and the 
copy and paste mechanism of X depends on the middle mouse button).
Any ideas to get this working (other then using 3 button mouse emulation by 
clicking left and right mouse button at the same time) ?

greets,
Staf.
