Keyboards and Keyboard/Mice Combo Sets

[Jeckal]

I have bought this wonderful keyboard+mice set I got no problem using it at all. However, when I put the computer in sleep mode, after wakeup the mouse and keyboard doesnt work. Everytime I have to power off and then on the computer which is not good for the OS. I have tried unplug and replug the receiver but that didnt help also. What should I do?
