So, I don't know if this is where the problem lies or not, but I guess we'll see...

I got a new mouse. optorite ML101....1600dpi laser mouse. Cool! works great most the time. But, every once in a while, when my computer is working hard, it slows down and get's chunky.

I watched windows task manager, and did something that I know would cause it to slow down, I opened up a folder of movies (windows looks at the duration and resolution for each one). Sure enough, my mouse got slow and chunky.

What I saw it task manager is what I have the question about...should there be TWO instances of "explorer.exe" when I open a windows folder? the second one was eating 80-90% of my CPU

I did an "end task" on one, and it closed the folder. I did an "end task" on the other, and it killed my taskbar and desktop folders. "new task" > "explorer" and my task bar was back. opened the folder, and again, a second instance of explorer.exe started up.

Should there be two instances? And is there some way to tell it not to eat up all my CPU to the detriment of my mouse?

Is this something I just never noticed before because my mouse hasn't been sending enough data to be picked up?

Is there some better mouse drivers besides win XP's stock mouse drivers that I could use?

Explorer is the shell in windows and it controls all file/folder access while it's loaded. It also is your GUI. Even though it is split into multiple process threads it should only show up as one instance. I'm not sure why it's doing that. The manufacturers drivers may work a little better...

Yeah, there should always be just one occurrence of explorer.exe running... High spikes of CPU usage could mean few things... like a spyware or virus... or some kind of memory leak/program bug.

I'd recommend installing the latest Optorite drivers and not use Windows ones...

Zemo

optorite doesn't have drivers for this.

Ran AVG antivirus, Spybot S&D, and Adaware Pro, and came back with nothing.

If you can try lower dpi, try 1200 or 800. See if that fixes the issue...

Zemo

nope, can't change the dpi...

I assume it's a USB mouse. Have you tried using a different USB port?
Also, are you up-to-date with SP2?

Zemo

I'm up to date with SP2, yeah. lemme try a different USB port now...

hmm, no change.

Optorite mouse page

The link contains a pdf file that shows how to tone down the sensitivity.
Basically, go to "Mouse" in "Control Panel". Hit settings tab and then turn down mouse pointer sensitivity. That's all they have...

Give that a try... besides that, it seems like a dud or maybe a bad mouse??
