I'm looking for a good quality 4 port PS2 KVM switch. My primary concern is trouble-free switching (see below) and PS2 emulation so I can reliably start a PC in the background and have the mouse/keyboard work when I switch to it. I currently have a Belkin Omni View SE 4 port switch (PS2 ports). I use a Logitech cordless wheel mouse and keyboard with it. Everything works fine until I switch away from my main computer. When I switch back, the scroll wheel on the mouse doesn't work until I reboot. It still works on whatever other computer I'm controlling, just not my main machine. I found a few things about it on Google, but nothing that helped.
