The double click on my Logitech MX620 Mouse is periodically unresponsive and sometimes when selecting text, it sticks and highlights several lines instead of one word. What's the problem and what can I do about it? Thanks

Learning how to cut and paste can make your life on the computer much easier.
It saves time and is more accurate that retyping the information, particularly if you do it several times.
If you know how to highlight words on your computer, you can easily copy sections of text and paste them somewhere else.

Open a text document or an email that contains some type.
Click at the end of the block of text you located in Step 1 and drag with your mouse back to the beginning of the text to highlight the entire block of type you wish to copy.
Release the mouse. The selected area should be highlighted in a color, usually blue.

Right-click the mouse on the highlighted text and a drop-down menu appears.
Select "Cut" to copy the highlighted text and remove it from its original position.
Select "Copy" to copy the highlighted text and leave it in its original position.
Paste the text you copied.
Right-click in an editable text box and select "Paste" from the drop-down menu.
The text appears in its new location.
Alternatively, highlight the text and hold down the "Ctrl" key on your keyboard while you press the "X" key to cut the text or the "C" key to copy the text.
These keyboard shortcuts copy the text that is highlighted.
To paste it, click in a text box and use the "Ctrl" and "V" shortcut to paste.

Hi Arsenal,

My Logitech cordless occasionally does the same thing. On mine it was caused by a build up of gunk over the optical sensor. Once I cleaned it, it functioned normally.

I know it doesn't make sense as far as the buttons. I'm just sharing what worked for me. Hope it works for you.

Best regards
Mike

try reinstall mouse driver, probably fix-it

Acting on advice from another FixYa string, we blew out the mouse and dock several times with canned air. It performed slightly better, but then as we continued to use the mouse it suddenly cleared and is working almost 100% now.

From reading earlier strings, I'm wondering why Logitech (in its product material received on purchase) doesn't recommend this as periodic maintenance for the mouse?

Check the CCORNELL posting for the solution. Your mouse is double clicking when it should be only single clicking.

Yes open the mouse and clean the left click that should help if not is time to buy new mouse

you may have turned on click-lock. You can disable this feature in Control Panel, under Accessibility Options. Click Lock helps people who have a hard time holding the mouse button while dragging the mouse across the screen by holding the mouse button for them
