Rich, I don't feel I'm the one to solve your prob. You're lightyears ahead of me when it comes to experience. But, just to let you know, for what it's worth, I've been running Logitech's cordless Mouseware and their keyboards and mice for years, now, and no prob. with their stuff other than mice eating batteries in the older versions.
I don't use Active Desktop as it gave me probs in 2002, and I seem to get along well without it. WIN XP PRO< SP2, P4 1.4 proc, 512 RAMBUS RAM, ATI X700PRO 256 video, SB Audigy 1st version 5.1, Samsung SyncMaster 910 MP 1280 X 1024.
This is the place to get answers, so I'll get out of the way and let 'em come. Luck to ya. Thanks for all the cursors; still stuck on 'em for yrs, now.
