Yep! Sorta like all the computer problems that are fixed by a simple reset.
Oh wait! Let me share a strange PC problem with you. Ever since I got a
new joy stick that has lights, etc. and is powered by a plug-in converter,
(DC of course) strange things sometimes happen with my mouse. The mouse
will begin to skip and finally lock up randomly and intermittently. The
mouse cable and the joy stick cables ran parallel, sort of, going the same
route through a hole in my PC desk back to the PC.

At first, the mouse would do the lockup thing fairly frequently but only
when the joy stick was removed from the desk top. The joy stick was set up
for easy removal by break-away connectors mounted inside the keyboard
drawer. This meant the cables were still running parallel but that the joy
stick power cable was lying open, with DC on it. Next, I rerouted the mouse
cable so that it no longer ran parallel with the joy stick cables, except
where they all plugged into the PC. Problem solved - or at least I though
it was. Sometimes, but rarely, the mouse will still skip. It is easy to
fix now - just grab the mouse cable and give it a few shakes.

My take on it is: There is an electrostatic event between the mouse cable,
its insulation, and the open, but powered DC joy stick cable. I am guessing
the mouse is being held "high" by a gradual build-up of a capacitive charge
between the DC and the mouse's cable insulation.

Any comments, guesses, etc?

Thanks for all the replies to my magnetic switch query. I finally got
time to completely disassemble it clean everything, ck continuity and
file the contacts. I found no shorts, bad wires or burnt
terminals...also it was mostly clean to start with. I reassembled and it
works properly and repeatedly. I must of chased the gremlin out ...he's
probably setting up shop in some other piece of equipment now... oh well
onto cleaning up the 38"x 73 1/4" cast iron top and wing.

In other words, you took it apart, looked at it, and put it back together
and it works? It's great when it works like that, isn't it! - GWE
