Hellp Everyone. I have an Acer Aspire 5570 Notebook. The cursor jumps to someplace else while typing a message. In fact it has occurred while typing this message. Usually it jumps to a place earlier in the message, but not predictable. Do you think this is a hardware or a software problem? I have tried using the built in mouse or a USB mouse. Same problem. I am currently on a Mexican cable out of Puerto Vallarta. Normally I live in NC where I use a cable with NC.RR.Com. Any suggestions?
