Writing on my nearly three-year-old Dell laptop
is extremely annoying as the cursor keeps jumping back to wherever the mouse is. I've replaced the keyboard and installed a new hard drive but the problem persists. What causes this and what
can I do?

DQ: This seems to be a hardware problem, not a software issue. I have had a similar experience and found the trackpad just below the keyboard was the culprit. As a touch-typist, I use both hands and nine fingers (my left thumb does nothing). That means
my palms occasionally touch the trackpad. Tapped with just a small amount of force, the machine
would think I had clicked on the mouse and wanted
to move to where the cursor was. Your problem seems to be the same.
First, look in the Control Panel and see if there is an option to turn the trackpad off and plug in an external mouse. Some models today do not have special drivers for the trackpad, which makes it difficult for you to
turn it off. In that case, contact the technical support team at Dell. You may also want to have a look at these links, www.applefritter.com  (search for 'trackpad problem') and weblogs.asp.net/israelio (search for 'dell'). Your problem is common with Dell machines.
I am interested in learning how to play classical guitar for free online. Is it worth it or should I just pay for private lessons?

DQ: As a 'musically challenged' person, I am
not sure I can answer this question. I suspect it depends on how dedicated you are. A quick search
on Google for 'free guitar lessons' brought up 509,000 hits. Have a look at some of these sites
but be careful: some that appear to be free are, in reality, not. As always, be wary about giving any personal information.
I cannot say if online lessons are better than studying with a teacher. I am sure you would be
able to get something out of a virtual classroom if
you are conscientious. If you already own a guitar, try one of the free online sites and see if you have what it takes. You'll know soon enough. If, after a few weeks you decide you want to continue, you may want to consider real lessons.
