Booting from OSX into Win7 or ubuntu kills my two finger scrolling in OSX:

Whenever I boot from OSX into Win7 or Ubuntu then back to OSX, I lose two finger scrolling. It's not a big deal, just really frustrating because it can only be fixed with a hard reboot (holding the power button)... a restart does nothing to fix it.

I'm trying to figure out how the kexts are loaded, and why booting into another OS would break two finger scrolling in OSX.

If I stay in OSX when it's working, I can do as many restarts as I want, no problem. But as soon as I switch, it never works when I switch back.

Does anyone know how the kexts are loaded with NBI, or generally? Or any ideas on how I can try to fix this? It's driving me nuts because it's the last thing til full functionality

I have a Samsung N310, Synaptics Touchpad....

Thanks!

I also noticed that my clocks in the different OSes were out of sync, so could the same thing that's causing that also be causing this trackpad issue? I'm just trying to figure out how the OSes interact and in which ways one OS can affect another.

I'm using the Meklort PS2 Controller & prefpane, so I might just try switching to the VoodooPS2Controller.kext unless someone has any ideas on what might be going wrong

One last thing - for some reason I can do ONE-finger scrolling (not edge scrolling) if I use my thumb or pointer finger. Any ideas????

If i put the computer to sleep and wake it up again I also get 2-finger scrolling back


DSDT issue? Software issue? Any ideas?
