Apple Blue Screen of Death?
Looks like Logitech is doing its best to make a Mac behave like a Windows Machine.
The evidence as of this writing indicates that every single instance of a “blue screened” botched Leopard upgrade is attributable to the presence of APE...The most common route is Logitech Control Center, the mouse “driver” software from Logitech. “Driver” in quotes because it’s utterly absurd and completely irresponsible for Logitech to base their mouse software on a completely and utterly unsupported-by-Apple system software modification.
