I went to visit my granny the other day with my family, and saw her computer. She has the following: AOpen PC running Windows 98 on a 350 MHz Pentium III, 64 MB RAM and a 6 GB HDD. She has some old crap keyboard, a crap Zitech screen, and a Logitech MX700 mouse. I tried out the computer, but something constantly happened. The mouse constantly lost signal. Suddenly it would move, and click, and suddenly it would stand still.I though it was the old computer cracking up, but then I tried the mouse with my MB (see sig), which I brought for watching movies in the car. The mouse did the same here. I daily use the MB with a Mighty Mouse, and have no issues here. The mouse was fully charged, and nothing seemed wrong with it. Is this normal, or is it a faulty mouse?
