Hi,
I don't know if this will help, but I just had the same problem yesterday on
my SOny Vaio laptop. Everytime I typed a few letters, the cursor would go to
a different spot on the page and the I would be typing there. If I typed
very slowly, then it worked, but as soon as I started really typing it was
Garbage. It turned out that the Laptop had the wrong mouse driver installed.
It had a generic P/S2 mouse driver when it really needed the ALPS touchpad
driver. With the wrong driver, vibrations from typing were being interpreted
by the ALPS hardware as scroll commands and other non wanted commands. Make
sure you have the CORRECT mouse driver installed. If you are not using a
tablet machine, make sure you turn off the pen entry nd handwriting ans there
are pen flicks that do strange things if mis-interpreted. If yu are using an
external mouse and you also have a touch pad, make sure the touchpad driver
is installed first, then install the external (USB) mouse driver.
I hope this helps.... It worked perfectly for me. Thank you SONY technical
support! They did a good job of figuring out the problem.
Good luck!
