Trackball (EB)

The mouse on my desktop PC has been behaving erratically for a few days so I have gone for a trackball replacement. I used to use one a few years back at work and found  I had less muscle tension than with a mouse so I'll see how this one goes.  Easier to fit it onto the desk with the pen tablet too.

Back-blipped as I had a migraine yesterday evening and couldn't see clearly for a while.
