Some mouse users complain about double-clicking when it should be
single clicking. So I'm looking around for information. One guy
says Logitech told him to remove the batteries and then click the
buttons 30 times. That would be for resetting software? Does that
mean the debouncing takes place in software? If that makes
sense... Do they use software debouncing to save money?

This is noncritical. Any general comments about the subject
appreciated.

I have a wireless mouse, Logic Tech or similar the right and left
button's actions have become reversed. Has anyone seen such a
thing? It's not a PC problem as another mouse works fine.

I believe it's a Windows setting for all mice. Just look in mouse
properties... Control Panel > Mouse > Buttons. Make sure the box is
unchecked.

Is the other mouse the same brand and model? They all use different drivers for the special features.

I turn off the touch pad on my laptop so I don't get palm swipes. It turns itself back on from time to time. Go figure.

I don't see how latency is introduced. The signal would be relayed
instantly. Any follow-up signal within X amount of time is
disregarded. Sounds simple enough. How else would it be done via
software?

The fact that the driver has to process it and determine if
additional noise is additional button presses or just noise and then
pass the decision on.

How can you say that does not take time?

instant reaction and a blanking period

I like the fact that you have explained to him how debounce could work without any perceptible latency and he is backpedaling saying debouncing at all would lose button presses. That's why I wouldn't explain it to him until he apologized. I knew he wouldn't apologize and even if I did tell him he wouldn't understand/believe even such a simple concept. The guy is really amazing.

You have your mouse settings in the Windoze Control Panel set to "left
handed" mouse.
<http://www.bbc.co.uk/accessibility/guides/mouse_easier/left_handed/win/win7/index.shtml>
There may also be a similar setting under "Accessibility" features.

Or, you could learn to use a mouse with your left hand, which might be
useful in the future.

Yes, I have used a 0.005uF.

It does work.

The small spark keeps the contacts clean.

And it's cheap, and easy.

Maybe I will try that someday if I wear it out.
