Right click not functioning as should

SOURCE: Wireless Mouse gets stuck

Take a eraser and use it to rub the contact points on your batteries clean. This seems to be the issue where your sensiativity will change by it self the the mouse has a 20 - 30 pause to reset it's self as if you just stuck a different battery in it.

just called Logitech support (who were more than helpful, very friendly, and picked up the phone within 5 minutes).
I have an MX3000 laser combo set and the receiver lost connection to the mouse last week. Then the keyboard went out a few nights ago. I had tried what everyone else here had tried to no avail.
So I decided to give a tech support line the benefit of the doubt and call one...
I'm very glad I did!
Here is the entire process for the Left Ctrl + Left Alt + F12 keys. First, when you hit these keys together, a box should pop up on screen to prompt you to reset the encryption sequence. That is what these keys are for. If nothing pops up on your screen (as was my case!), wait a few minutes for the button sequenece to time out, then hit these keys again. Make sure its L-Ctrl + L-Alt + F12 only. Within 2 seconds after that button combo, hit connect on the receiver. Within 2 seconds of that hit connect on the underside of the keyboard. Within 2 seconds of that, hit your Escape key on the keyboard. Sounds completely ridiculous, but this is the direction Logitech support drove me in. And it worked for me. And this is after I tried everything imaginable for over the past week.
We then moved on to the mouse, which i thought we had fixed. But now i have one working and one not working, so I think I need to re-run through this whole process to fix the second mouse. Basically, I now have 1 mouse that works on both receivers, on 2 different pc's with 2 different keyboards in two different rooms (both sets are MX3000 however).
The other now seems to have lost the signal. Will update if I get that second mouse to play nicely with me.
Hope this helps anyone about to trash a perfectly good unit like I was!

Hi, I have had the same problem with a Logitech Cordless Desktop setup. The mouse and keyboard had been used in an office environment for about two years, then the mouse would double click unexpectedly, would not hold items when trying to drag them and the right click would sometimes fail to work ...then sometimes it would work perfectly. I tried all the other suggested cures such as cleaning out the inside of the mouse, new batteries and reinstalling the driver which did not prove to be effective. A good clean improved things for a couple of days but the symptoms returned. At this point, I dismantled the mouse and resoldered some suspicious looking joints on the circuit board inside, especially those attaching the microswitches for the mouse buttons. Since then, none of the problems have recurred. I presume that repeated pressure on the switches over time had cracked the solder joints which caused the mouse to behave erratically. You could try this, but dont get the joints too hot or you will damage the switches or other sensitive components. Simon.

Do you have the Nano 2007 model, or the Nano 2008? Procedures are different. The following link should help you:
Link 1 (resynching mouse)

Make sure you have fresh batteries and they are aligned correctly. If it still does not work, download the latest version of SetPoint and reinstall the softwrae after uninstalling it first.

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
