For some time now, attempts to highlight unwanted text in newsgroup
replies etc. using *left click and scrolling* with a mouse have been
very flaky.
W7 pro and grubby mouse pad.

Have things moved on? Is it my tackle? Is there a keyboard alternative
to check the operation?



Maybe the mouse is slipping on the pad? You could try cleaning the mat
and the underside of the mouse, as grease tends to build up. You could
even try dispensing with a mat, if the top of your desk isn't too shiny.

Have you checked that the mouse's cable (assuming it's not a wi-fi
mouse) is securely attached at both ends? Have you checked with another
application - say your text editor - to determine if you see the same
behaviour there? Do you have the most up-to-date driver for your mouse?

If none of that leads to a solution, it could be that some internal
component of the mouse is wonky and - given how cheap mice are - it
might be easiest just to buy a new one.
