recently ive been getting some very clunky mouse movement, and sometimes button presses aren't registering. im using a Logitech V500 (that mini-wireless one) with its little USB peripheral, and im also using a wireless router situated at the other end of the house. its quite OK when its just my Powerbook, but if my laptop is accessing the wireless internet the mouse somehow acts like the batteries are dieing. could 802.11b/g signals be hogging the free wave space in my house or is my mouse slowly breaking? anyone had similar problems? i mean im getting this right now but everyone is in bed and no other electronics are on (ie. Microwave). hmmm!
