My RPC's mouse is playing up (it could just need a clean). Sometimes (well
quite a lot of times) whilst moving the mouse, the pointer stops in the middle
of the screen.

Any ideas anyone?

Clean it to start with and if that doesn't work, open it up and check the
alignment of the opto electronics. The ones in the school were abused badly
and required re-aligning every few weeks. To do this just keep rotating the
shaft encoder while gently pressing against the LED / phototransistor; when
the pointer moves smoothly it's aligned (near enough). It could be that the
RPC's mouse uses a 'set' type that can't be knocked out of alignment (never
needed to sort one of these) in which case a blast of air to clear out any
dust wouldn't go amiss.

Merry Christmas,

Pat.

Yep! Give your mouse a Christmas clean. Removing the ball and cleaning it
with a suitable solvent, may not be enough for solving the problem. Undo
more of the mouse by removing the two screws with a cross-bladed
screwdriver. Carefully remove the two black rollers with the integral
wheels and clean the roller part, that contacts the ball, with solvent.

You may find all sorts of rubbish stuck around these rollers which won't
help in producing a smooth pointer movement. Even more carefully
re-assemble these back so that the wheel is aligned between the light
emitting diode and the photo-cell assemblies. Re-assemble in reverse order.

Hopefully you will finish up without any parts left over. I added a Mozart
board to my RPC last weekend: has anyone lost a large spring? I joke not!

Are you sure it's not off one of your flaps.

As well as cleaning it, check that your mouse is not in direct sunlight - if
so, drawing the curtains may have a magical effect!

I have found that a bar of soap and a nail brush works wonders!

Yes, clean the rollers as well!

You can clean them without taking the mouse apart. Just use your finger nails
to remove the bulk of the dirt that builds up, and then a cotton bud dipped
in IPA to make them really clean.

Yeah... it's amazing how quick it builds up as well!

Yep.

The only spring I can think of is the one for the flap... but mine is in place.

Cheers,

Pat.

Since I started a piece of Suede leather as a mouse mat i have had no troubles
with my mice, until they are worm out completely. I used textile tape to affix
the leather to the table and it is wonderful at cleaning the mouse while acting
as a slipfree surface. If only the Macs I use professionally had the same type of
'mat' ....

Suede, c'est bon!

Spoken by a Swede ... M. X. & A H N Y!

There are three things you need to do.....

1. Clean the rollers and the ball.

2. get a good mouse ball, to replace the pathetic foam one.

3. buy a 3M 'Precise Mousing Surface' about 10ukp.

Hope this helps.

John.

Can I second that?! I think I must be one of the few people to actually have
bought TWO of them - one for use at work and one for use at home. They are
wonderful! NCS sell them.
