Hi. I'm having problems with my mouse although I can't be sure if it's just a mouse fault or a more serious computer fault. Here's what's happening:


Clicking has no effect unless you click something rapidly for about half a dozen times.
By just moving the mouse (not clicking) it'll highlight the text on webpages, drag taskbar buttons, drag the 'play position' button on a video player etc etc.


Doing a 'left click' on an empty part of the screen can restore normality but usually not for long.


It's a Logitech wireless mouse/keyboard and I've updated the software. My main AV and also Malwarebytes give a clean report. I use Windows 7 64 bit.


Can anyone suggest a cause and cure for this problem? My thanks in advance.
