Such as "I have a Logitech mouse and installed their driver..."
I'm running OS 10.5.8 on my iMac, and sometimes when I put it to sleep, it immediately re-starts. I'm not touching anything that would turn it back on, and all applications are closed. I end up having to shut down. This started a couple of months ago. It doesn't always happen, but lately it's been worse. Sometimes I just open safari or check my mail for a minute, then try to put it to sleep if I won't be using for a little while, but I end up shutting down because it keeps coming back on. I can't find any pattern to this either. What could be causing this and how can I fix it?
