whenever I have one mouse and keyboard working it freezes the second one and will not let me click anything with the second mouse if I do it stops what I was doing with the first mouse. I just want to use them both at the same time without freezing the other one. can I get something where I can lock a keyboard and mouse to 1 screen and the other keyboard and mouse to the other screen and be able to use them without the other freezing/pausing?
