What OS are you running?

  A dual-core CPU, or an older dual-CPU system, can be executing two 
instructions at the very same moment.  Those instructions shouldn't ever be 
part of the same process, *unless* that program has been designed to do that 
safely -- and in some Windows versions these simple little tools are not.
