Connecting USB mouse turns OFF touchpad

Hi,

I know that there were more then a lot topics about this but none of them explains my situation.
Here it is:

When I am connecting mouse to my Macbook Pro (any USB mouse) touchpad stops working immediately.
The problem is I want to have touchpad ON not OFF when the mouse is connected. Then problem can be fixed temporary when I reboot the system - mouse and touchpad work.
The worst part is that even after I reboot (mouse + touchpad work) disconnection mouse froum USB makes my Touchpad not working.

Also it's worth noticing that all the Multitouch functions on touchpad work all the time, I can enter Mission Control and so on, every time mouse is connected the "pointer" funtion stops to work - ONLY REBOOT FIXES THE PROBLEM:/

I already tried changing the setting in system preferences "touchpad disabled when mouse connected" - no help.

I am using SmoothMouse app, maybe that's the problem?

Please help.

Problem solved! If you use Smoothmouse and you don't want to use it with trackpad you have to check "enable for trackpads" and choose Acceleration OFF.
Thank you for help.
