Long ago, various pieces of the system cleared out the top bits but it
looks to me like all that code is gone.  A little debugging should
tell you where the problem is.  Put a print into
/sys/src/cmd/rio/rio.c, in the routine mousethread(), right after case
MMouse.  Print out the state of mouse.buttons.  If the button is
cleared there, it's the library (/sys/src/libdraw/mouse.c); if it's
still set here, then rio is doing it somewhere.  I don't have an
intellimouse handy but this should be easy for you to track down.

I'm using Microsoft Intelli wheel mouse now.

Without rio, I rolled up and down the wheel while doing
`cat /dev/mouse', and its button state of the output was
`8' or `16'.

But under rio, `cat /dev/mouse' produced with the button
state `0' only.

Could you tell me what is happening and why?

I want to change rio to interpret this 8 or 16 button state
as either arrow-up or arrow-down keyboard event.
