I had the AMD dual core drivers, and the dual core optmizer installed before I found AH. After installing AH I had the spinning clipboard, lockup/crash prob.
I installed the windows KB896256 XP patch, didn't fix it. Even running in every different compatibility mode, nothing worked.
I uninstalled the xp patch [careful if you uninstall KB896256. it also uninstalls over half of your drivers for everything sound, usb ports, video and more. at least it did for me] and the dual core optimizer.
I then ran AH in '95 comp. mode and it works great except for the warpiness once in a while not very often though. But with everybody else having it too I'm hoping that will get better on it's own.
