Mouse problem: Why does my wireless optical mouse suddenly jump to the bottom of the screen?
From time to time when I use a Microsoft wireless optical mouse on a computer running Windows 7 Professional, the mouse pointer jumps to the bottom left corner of the screen, usually just as I’m about to make a click. I’ve tried uninstalling and reinstalling the mouse without success.
If you download and install the latest driver file for the mouse from Microsoft’s site and the problem still occurs, it’s a wireless mouse, so make sure that the batteries are new or are fully charged. Optical mice tend to be very sensitive to the material they rest on, so make sure that you’re using an optical mouse pad or other suitable surface. Is there a radio or another wireless device near the computer? If there is, the problem could be the result of radio interference. Pet hair, etc., can get stuck in the region near the optical sensor and the mouse interprets it as movement, so turn the mouse over and have a look. Use a pair of tweezers to remove any debris.
Does the same behaviour occur when you use a traditional wired mouse or move the computer to another room? If none of those suggestions are helpful, check the sensitivity that is set for the mouse under Start => Control Panel => Mouse. Go to the Pointer Options tab and experiment with the settings.
Mouse problem: My Microsoft Wireless Optical mouse will not work after I have left it for a while unless I click the left button
I am using Windows 7. My Microsoft Wireless Optical mouse that is attached to my laptop computer via a USB hub will not work after I have left it for a while unless I click its left button. After some experimentation I found that it works – the pointer moves – if I move the mouse within 60 seconds of the last time I used it, but at 61 seconds or more, I must click a button to make it respond. This sometimes causes trouble when the mouse is focused on top of something that I didn’t want to click.
You should have specified the model.
Open the Control Panel and double-click on the Mouse icon. Click on the window’s Wireless tab, which only appears if a wireless mouse is installed. Check the Battery Status. If necessary, replace the existing batteries with new ones. If that doesn’t help, find out if your mouse has the option of different channels that enable you to tune to a different frequency in the event of interference from other wireless devices. Retune the mouse’s frequency.
Read the user manual, or check Microsoft’s site to find out how to do that if you can’t work it out by looking at the mouse and its receiver.
