I am gonna try hooking kb & mouse to my lappy later today to rule out any possible software issues, but this is totally intermittent!
KB was still on this morning, when I woke PC from sleep and 10 minutes later... gone! This is very frustrating!
Rather than double posting I am UPDATING
I tried the kb/mouse combo on my laptop... same result, and this time I tried it without the Intellipoint drivers
1st. KB lost connectivity in 5 minutes, added IP drivers and same result. Called MS technical support and they are sending me a new kb/mouse!
