i am having an annoying problem with my Logitech G5 v1 mouse that i had for over 2 years. For some reason, this started about a week ago, every so often it stops working. The sensitivity led light on the top turns off and and mouse becomes unresponsive for about 5 seconds. After 5 seconds it comes back on and all is good again. The light on the bottom however does not turn off during the ordeal. i really don't want to buy another mouse cus this one is just perfect for me... and i am pretty sure logitech does not make the original orange version anymore : ( HELP!!!
