I recently bought a Microsoft Arc mouse and Logitech M705 mouse. The keyboard came first and so i plugged that into my pc and downloaded all the relevant drivers and it was working perfectly. Today my mouse arrived and after installing the software and drivers for that im finding that my keyboard isnt working as well, often it will just randomly stop typing one letter, sometimes it will be fine, its not the keyboard goign to sleep as i will be using it and then for some reason 5 letters wont work (i say 5 because thats the most number of different letters that havent worked in a word i know ive typed but haven't appeared on screen.)

does anyone know what the problem maybe? i assume it is software related..i have tired uninstalling th elogitech mouse and reinstalling but the problem persists
