I've got one of those MS optical "intellimouse" mice which is just your basic optical mouse with browser back/forward buttons on the sides and a scroll wheel which also clicks as 3rd button - one of [url=http://www.microsoft.com/hardware/mouseandkeyboard/productdetails.aspx?pid=004]these[/url] to be precise and it's developed an extremely irritating problem. Sometimes (it's getting close to 50% of the time now) when I click the left (main) button it acts as though I've double clicked. I'd like to open the thing up to see if maybe the microswitches just need a bit of cleaning but I'll be damned if I know how to open one of those things up. Looks completely sealed to me. Anyone know if it's possible? Otherwise it's a trip down to FNAC for a new mouse. Michael.
