Query: WHAT A DISAPPOINTMENT!

NOT WHAT YOU WANT IN A TROUBLESHOOTING BOOK AT ALL. VERY LITTLE IN THE WAY OF EXPLANATION. HARDLY ANY GOOD SYSTEM ANALYSIS. ASKS YOU WHAT THE PROBLEM IS, THAT PROBABLY ISN'T THAT WHY YOU BOUGHT THE BOOK. IT IS SUPPOSED TO HELP YOU FIGURE IT OUT. SAVE YOUR MONEY KEEP LOOKING AROUND. THIS COPY IS COMING BACK.
