Logitech wireless mouse not following orders from Blender

:spin:Since moving to the Blender 2.5 series, I have been having problems (say BIG problems) with my wireless 3d mouse. (Before I continue, I would like to inform you that it worked perfectly with 2.49.) It does not resonse to any commands from the preference menu.
The only thing that it does is CTRL+LMB,SHIFT+LMB, LMB,RMB and ZOOM with scroll/MMB.
If it is the mouse incompactibility, I’m ready to change it, BUT I MUST BE SURE:confused:
please help a Noob otherwise I’ll be leaving Blender again:(
Regards and thanks
