I do not know where you work, but wheel mice are the norm everywhere I work. It worked before so as far as I am concerned some change in this latest kernel broke it. I have had this kvm for 3 years without a problem. It worked with RHL 7.3/8.0/9, FC1, FC2 until now. I just looked in bugzilla and saw the same suggestion. The problem is that for me not having my wheel work is just as bad as not having the mouse work. I am used to having it so if it does not work, I will waste time scrolling the wheel. I realize some of the software in the kvm's are crap but they are not going to go away. At the very least Red Hat should put some of them on the HCL and say these are supported. At least then I would have an idea what to buy. The way things are now it is a crap shoot and even if you get one that works perfectly today, tomorrow some change to the kernel might break it. If the one I have had never worked I would have sent it back. For obvious reasons that is not an option now. One other thing I have noticed, with the old kernel switching between the different machines with the kvm was instantaneous. With the new kernel there is about a 1 second delay. Something changed and it is not for the better. Regards, Tom
