Sleep wonky?

[R Bygrave]

Am actually glad you took the rant as not directed at you, which was the case.

So there's no keyboard wake-up call for a confused Mac?

I actually posted this comment on a blog community, where I got given the answer 'swap to USB -- it might well sort out your issue because USB is more standard between PC and Mac'.

It's not a great answer (it would require swapping out the firewire adaptor and no longer having the second firewire port immediately available) but I suspect it's a better real-world solution than the options I was trying to think off...
