Dr. John's "Surefire Fix" to solve your problems
Just buy a nice power strip or surge suppressor and plug the Mac and related peripherals into it (as I do).
When you shut down, just reach down and turn the power strip OFF.
When you want to reboot, reach down and turn the power strip ON.
Do this, and I _guarantee_ that you will NEVER be bothered by such problems again!
