For the past couple of months, my Toshiba Satellite laptop has had a very strange and annoying problem. It seems to be in the mouse/HID driver subsystem. It is using XP MCE with SP3, current on the updates.
I use this laptop both at home and in the office, and have separate mice in each place. It worked fine for over three years. This past summer, the little home mouse failed, so I bought another one at Staples. It turned out to be horrible (no detent on the wheel), so I bought yet another one, an Agama, at a different store. It works a little better... but somewhere around that time, the system went gaga.
When I use the mouse now, either home or office (so it's not a bad mouse), it sometimes freezes up, typically for around 3 seconds, but not precisely. During that time the Synaptics touchpad still works, not that I ever like to use it. That's annoying. Worse, the mouse often acts as if I had just pressed one of the three buttons. It might be any of them, though the right is most common, so the context menu just pops up now and then, but it also can left-click on a button when I don't want it to, or open the middle-button scroller. One other detail is that when I move and unpack it and come out of standby with the different mouse attached, it takes longer than it used to to find the new mouse. Sometimes around a minute. BTW the office mouse shares a port with a keyboard via a PS/2 adapter, but that has worked fine for years.
The internal keyboard also jumps around a lot. I use it with an external keyboard at work and that usually is okay, but the internal keyboard can't go for more than a few lines of text without jumping a few lines away. Yesterday, for instance, I was typing email text and it jumped into the address field. I have to use control-Z a lot! It doesn't insert characters, but it sure does act as if I were touching the Synaptics pad, even though I'm being careful to maintain my distance.
BTW the Synaptics widget has disappeared from the taskbar, and there's no tab for it in the control panel's mouse section. I seem to have lost all controls for the touchpad. Anybody know where they are? That could be related, of course.
I've used a few malware scanners and they haven't found anything, so I don't think it's malware, though that would be an obvious answer were it the case. I'm thinking it's the HID drivers. The control panel shows one "PS/2" device and one "USB human interface device". But the device manager itself shows two entries (that look the same) for USB Human Interface Device, one for "HID Complaint Device" and one for "USB compliant consumer control device".
Any suggestions? Thanks!
