Hi, Has anyone with two computers had interference problems using two wireless keyboards/mice (wk/m) on the same desk, within 12 inches of each other? The receivers are 3 feet apart. I have a Logitech Mx Duo wk/m on one computer, and for a while had a Dell wk/m on the 2nd computer, and there was no interference. But the Dell wk/m was USB only, and didn't work right on my older Dell 4100, so I disconnected it and when back to wired k/m. But I miss the wireless, so I want to get another wk/m for the Dell, but this time with PS2 connections. I think the Dell k/m's are made by Logitech, and I didn't have interference before. But if I get a 2nd Logitech wk/m similar to my present Mx Duo, maybe they are close enough that intererence will occur. Has anyone run two Logitech wireless keyboards/mice together successfully? Seasons Greetings! davez
