hey people picked up a shiny new Logitech MX Revolution today, i tryed installing it on my dell 6400, i followed all the instructions, ie. leave it charging first etc. but no matter what i do the mouse doesn't respond, when i plug in the receiver it "installs" the drivers "Logitech HID-complient cordless mouse" and the battery bar apears and disapears as it should but i can't get to respond to movements, scrolling, clicking etc. i've got the latest setpoint installed. It also shows the mouse in setpoint asif everything is fine. thinking it was my windows install i decided this was as good a time as any to give vista a 2nd chance, i installed vista, updated all drivers, got setpoint etc. etc but its the same story only now the mouse isn't appearing in setpoint, can anyone help me!!
