Wireless Mouse and keyboard from different brands

Hey I bought a Logitech MX Revolution yesterday and I also have a HP Wireless Keyboard (dont know what model). The thing is my mouse is acting a bit wierd like it skips around a bit not much but it doesnt feel like my old mouse which was also a HP and ran through the same reciever as the keyboard.
Could the signals be interfeering with eachother? I plugged in my old G5 corded from my other computer and it worked fine.

 

Try turning the keyboard off and see if the problem persists. If not, they are most likely interfering with each other.
