StateSave functions don't work-Wund Waker

[richardharison]

I was wondering why the F!-F8 statrsave/load functions don't work in Wind Waker.
They will work once and then not at all without using the menu.
Stop & pause seem OK Fullscreen freezes everything
Dolphin 3.0
Intel quad core @ 2.4Ghz
2 GB ram
Win XP SP3 32 bit
Nvidia 9800 GTX+

Thanks in advance
