Regardless of which program I am in, all of a sudden the cursor of my Logitech MX700 wireless mouse starts going all jittery. It will move very slowly, almost like trying to pull some squirming jelly-fish across the screen. It is very difficult to control and all I can do is reboot the PC, after which it is back to normal. The problem comes up anywhere from 5 minutes to 4-5 hours after booting. Hardware Environment: Home-built, MoBo Asus A7V333, AMD Athlon XP-1900 with Zalman flower, 2x256MB Corsair memory, 2x80GB Seagate Barracuda IV, Matrox G550 32MB AGP-card, Belkin F5D5000 network card, MoBo-integrated sound, Logitech Internet keyboard (without any drivers loaded) and the problem-giving Logitech MX700 wireless mouse, it's base attached to a USB 2.0 port. My problem occurs on USB 1.1 and PS/2 ports as well. According to Asus-Probe, my MoBo temperature = 30C and the CPU = 27C. Software Environment: Windows 2000 Pro with SP4, Norton AV 2002, Agnitum Outpost Pro 2.0 Firewall, Diskeeper 7 Workstation (set to "Set it and forget it"). MS Office 2000. CPU-Idle 6. VIA Hyperion 4in1 V4.48 drivers. Opera 7.11 and Avant 8.02 Browsers. IE6 is installed, but I never use it, nor do I use Outlook (Pegasus instead). Currently using the standard Logitech mouse-driver 9.70 (as built-in from Win2000). I have tried all sorts of mouse-drivers from both Logitech and Micro$oft. All give me the same grief. Before, I had the corded MS Intellimouse Explorer 3, and that one completely froze both my keyboard and the mouse, only a hard reset could remedy it. Again, regardless of being connected to USB 1.1 or 2, or PS/2. Any help would be greatly appreciated.
