wireless problems

Hi,
Santa brought me an Apple wireless keyboard and mouse. They work great, but after I put the computer to sleep, I'm having problems waking it back up. I set up the Powerbook with OSX (10.4.3) so that the combination Open Apple-option-Z puts the computer to sleep. When I was using the USB keyboard, hitting the space bar brought everything back. Now hitting the space bar does nothing. I have to hit the power button on the Apple Cinema monitor to bring the computer back on, but I'm finding that the wireless isn't working or else, either the mouse or keyboard work, but not both at the same time. What's up and how can I wake the computer back up easier and have my wireless keyboard & mouse working. Or do I just have to wait for the wireless-ness to reactivate??

Thanks in advance.

I sometimes have to hit the spacebar a few times before the ol' girl finally wakes up. It's usually running about on the second hit though. Then, I hold down the mouse button and swirl her 'round for a while until she reconnects. Holding down the mouse button speeds this process up.
