mouse buttons problem - need help ?

[Mehmet Fatih AKBULUT <mfatihakbulut@gmail.com>]

hi all,
i've been using debian for months but still not able to use my optic mouse effectively as i did with XP.
it has 4 buttons and 2 scrolls.
buttons : 
            left - right (as exist in every mouse)
            backward - forward (backward is at left side of left button and forward is at right side of right button.)
scrools : 
            one is to move up - down in a page and the other is to move left - right in a page.

my mouse definition in xorg.conf is like this :
Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/psaux"
        Option          "Protocol"              "ImPS/2"
        Option          "Emulate3Buttons"       "true"
        Option          "ZAxisMapping"          "4 5 6 7"
        Option          "Buttons"               "9"
EndSection

what am i doing wrong ? dont know how to change these Options ??? 
any idea ?

now let me tell what my buttons and scrolls do :
buttons : 
            left and right buttons work fine. [no problem with these guys ;)]
            backward: button do something nearly the same as F5 ;) i mean it does something like refresh but still havent completely understood cos soon it refresh the page goes to bottom of the page.
            forward : does the same job as right button does. [shows me the properties.]
scrolls :
           first scrool also does his job pretty good. but second scrool [expected to move left - right in a page ] does what backward - forward buttons have to do. i mean it moves among backward - forward pages.

this is the biggest problem that i've for months since i've moved from ms to linux. ;)
hope you will help me and i'll fix this.
by the way did some google analysis but couldnt find any valuable info for 6 buttons :'(
thanks in advance.
bye.
