KVM Switches and Wireless Devices

I use a Belkin 2 port KVM switch with audio to control two machines. When I
try to use a wireless MS Intelimouse and keyboard, they do not seem to work.
When using these wireless devices, the mouse is very slow, jerky, and
difficult to click when / where I want to. The keyboard seems to work better.

If I use a standard wired mouse / keyboard, the KVM switch works great.

In contacting Belkin, they are telling me that KVMs in general do not work
well with wireless devices. The recommend using standard connections.

Does anyone know of either a work around so that I can use my wireless
devices (preferred), or another brand / type of KVM switch that works with
them? Any information would be greatly appreciate.

Thanks.
