[Anonymous]

Hi
I have a logithech LX mouse that use evdev driver
my xorg version is:
X.Org X Server 1.6.3.901 (1.6.4 RC 1)

my only uncommented lines in imwheelrc are:
---------------------------------------------------------
"^Dolphin$"
, Thumb1, Alt_L|Up
, Thumb2, Alt_L|Left

"^konqueror$"
, Thumb1, Alt_L|Up
, Thumb2, Alt_L|Left
#, Left, Delete
#, Right, Control_L|z
#"^gwenview$"
, Left, Control_L|F11
, Right, Control_L|F12

"^kpdf$"
, Thumb1, Alt_L|Left
, Thumb2, Alt_L|Right
--------------------------------------------------------------------

the problem i that imwheel works well in konqueror and dolphin but xev and firefox (I don't know if other applications do) do not recognizes buttons 8 and 9
there is some solution ?
thank you
