I'm using Zeph's 10.5.2 on AMD, and it's working almost flawlessly. The thing is, after a few hours, os keyboard shortcuts stop responding. Application shortcuts work ok (copy, paste, whatever) but anything system-wise don't (exposé, spaces, dashboard, grab, etc).

I'm using the latest AppleSMBios.kext, Mac OS X 10.5.2 (9C7010) Kernel 9.2.0. Keyboard and Mouse are PS/2 (well, keyboard is actually USB but I'm using an adapter).

Any ideas on why this may be happening?
