XP SP2. Frequently when I click the left mouse button Windows does not
see the click. I have to depress the left mouse button and conciously
hold it down for a second before Windows registers a click. Is there
any way to reduce the amount of time the left mouse button must be
depressed before Windows XP "sees" the button click?

Note that the problem is unique to a single click. I can double click
very fast and Windows always sees the double click.

I am using an MS optical mouse with very good tactile feedback and the
button makes a pronounced click sound when depressed so I know that I
am depressing the button far enough to make contact. The mouse is
connected to a USB port.

The switches will "break" (move past the indent and make the click
noise) before "making" the circuit (closing the circuit). So it is
possible to get a click without the switch actually making the
circuit. This is very similar to the latest breed of keyboards that
use a rubber membrane with carbon underneath that has to press against
the foil on the PCB to make the circuit; however, the rubber will flex
and "break" (where you feel the give or indent when you press) before
the underside has actually touched the foil, so similarly you might
feel the key has "clicked" but it did not make the circuit.

Check if clicking fast but HARD (i.e., smack the mouse button) gets
the mouse working. If so, the mouse switch is damaged or worn and you
need to get a new mouse. I've been through many mice where, yeah,
they click, but the switch is broken (or something else inside) which
prevents the computer from seeing the event.

You can always change the double-click speed in the setting of the
mouse properties: Control Panel > Mouse > Double-click Speed.

Thanks for the information. I will do some testing. Since the problem
is intermittent your analysis of the possible cause makes sense.
