I have a logitech mx610 laser mouse that I have used with my vaio laptop with windows XP and never had any problems. This summer I bought a HP 4830f desktop computer that has Intel quad core 2.4Ghz, 4Gb of ram, nvidia geforce 8500 GT video card with vista x64, and I usually always have some type of mouse lag, it is especially really bad when anything is downloading. does anybody have a solution for this issue, it is so annoying
