If I've left it like that, it's for a reason
I'd gone away for a few days, leaving my computer, which was also the family fax machine (which may or may not have been relevant to the issue) on. I'd also left the top cover *off* the trackball as there was a problem with one of the optical parts which meant it wouldn't move well horizontally with the cover on. I intended to obtain a new one as soon as I could find a suitable one.
For some reason, my sister needed to use my computer for something, so she called me (either on my mobile phone or possibly where I'd gone) for some guidance. During the call, she complained that the trackball was difficult to move horizontally. I thought "Oh, it's worse now" - no, I got back to find she'd refitted the top cover!
If I've left a cover off, there's a good reason for it. However, I'd now *hide* such a cover because of this incident.
