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.
