This is a software problem. Touch typing causes odd effects like cursor jumping back at random, weird programs starting up, and other badnesses. Impossible for typing. There are two bugs causing this behavior that are correctable. First bug is that the touch pad is active, so that stray finger touches turn into mouse clicks, which make a lot of bad things happen.
Touch pad fix. Do the Touchie-Swipie thing on the right hand
screen edge and touch the gearwheel charm for "Settings" Touch
or click on "Personalizations".
Click on "Ease of Access" (text string in lower left hand corner. Click on "Make the Mouse Easier to
use." Click on Mouse Settings (text string toward the
bottom. When the Mouse Properties box
opens, select the "Touchpad"
tab. Uncheck all the boxes. Then check "Disable internal pointing
device when external mouse is present".
Write all this down somewhere,
you will probably need to repeat this because Windows sometimes messes this
setting up. This one fix will cut down,
but not eliminate the flakie-wakies.
Sticky Key turn
off. I think this is an HP Bios
bug. HP makes some keys
"sticky". Not sure what sticky
is supposed to do, but it is bad for typing.
Press the left hand shift key FIVE times. This will bring up a little window that
allows you to turn off sticky keys.
Once BOTH patches
were applied the keyboard works well enough for touch typing.
Wasn't that easy?
