I changed my OS form vista to windows 7 home premium 32bit, since changing I'm facing problem when I'm typing.
The typing arrow move by its self while typing. for example if I'm writing a sentence the arrow suddenly move to beginning of the sentence or middle etc.
example : *I'm typing now* - * I'm tynowping*
its like I'm clicking there but I'm not!
I'm using Lenovo T400 and I updated all the drivers
