I kinda found out that it might have something to do with the receiver (or maybe not.....) Â The receiver is plugged in on the left side of my notebook, and I use my mouse right handed (so technically there is a notebook in between). In this setting I have mouse stutters. When I place the mouse alongside the receiver (on the left side) there are no stutters. Also, when plugged in via USB it is all working as is should [no stutters]. Â I guess this leaves me thinking that this has something to do with the USB receiver not working as it should be. It cannot be distance related, because this setup must, and should, be working on a distance of about 60 cm.
