mouse wheel does not pan

I tried to replace wired mouse with Logitech wireless M705 and came across the problem the roller wheel stop panning when pressed down.

I started investigating it and found the following

1. Roller is panning when pressed down for wired mouse from Dell and Logitech
2. When Logitech driver setpoint is installed panning for Logitech mouse stops but with Dell mouse continues
3. Wireless M705 does not pan regardless of the driver installed

I looked over the Cadence PCB forum and CAD forums and found that this is frequently sited problem.

Here is the ENV file settings related to mouse in my ENV file:

#--------------------------------------------------------------------

# MOUSE WHEEL SUPPORT

#   Environment Variables - Note quote variables so they are evaluated

#        at button time not when this file is read.

#   - _wheelcnt variable is set based upon number of detents wheel moved

#             range is -4 to 4 (no 0)

#   - sx1 and sy1 are cursor coordinates when wheel is moved

#

# Button values

#   wheel_up:   when wheel is moved up

#   wheel_down: when wheel is moved down

#   wheel:            up/down if either of above 2 buttons are not assigned

# 

# Keyboard modifiers (note we are case insensitive)

#   S - shift key

#   C - control key

#   SC - shift and control

#     Example: SCwheel - for wheel button assignment with both shift & control keys

#

# Button factor may be factorion (e.g. 0.5)

# lower number means smother zoom in (Vadim’s comment)

set buttonfactor = .1

button wheel_up "zoom in $buttonfactor"

button wheel_down "zoom out $buttonfactor"

button Cwheel_up "zoom in $buttonfactor"

button Cwheel_down "zoom out $buttonfactor"

#---------------------------------------------------------

it seems that knowing the variable for wheel pressed  and pan command can make it work.

Could you please advise where I can find the documentation for all mouse functions and wheel variables?

thanks vadim
