Mouse Or Touchpad Acting Erratically

The mouse or touchpad is a very important piece of hardware that is used to navigate folders, launch programs and access the right or left-click options. Sometimes users may face issues where the mouse or touch pad starts moving around erratically, and merely pointing the cursor on an icon causes the program to launch automatically. This issue is also known as automatic click issue. The most common cause of this problem is an outdated driver. The solution lies in updating the required driver by accessing it from the menu option concerned.

By default in Windows 7, when you hover your mouse pointer over the “All Programs” menu or other defined menus in the Start Menu, after a brief moment Windows automatically opens the submenu. This assumes that whenever you hover your mouse pointer over a menu, you mean to expand it.

If you do not like this behavior it can be disabled.

1. Right-click an empty area of the taskbar and choose “Properties”.

2. The “Taskbar and Start Menu Properties” multi-tabbed dialog box appears. Click the “Start Menu” tab.

3. Click the “Customize” button.

4. The “Customize Start Menu” dialog box appears. Scroll down and uncheck the “Open submenus when I pause on them with the mouse pointer” box.

Disable automatic submenu expansion in the Start Menu on mouse hover in Windows 7

5. Click “OK” on the dialog boxes to close them.

While using any of the application or even viewing my photo gallery the following events happen -

1. Automatically all applications are getting closed, start screen appears
2. Start screen then minimizes ( similar to the way if we have pressed and hold the back button),
3. Start screen then maximizes and after that ‘bing’ opens up automatically.
In all the above steps, phone also vibrates.

Originally thought it might be a SIM problem as was using a GPRS SIM and it was cut by the dealer at the time of purchase. Without putting the SIM, used the phone, but getting the same issues. So, guess we can conclude not a problem with the SIM.


This is a very annoying issue; when I was typing on my laptop my cursor would jump around, and putting the mouse pointer over an icon would automatically launch the program without any human intervention. Even after disabling the touchpad of my laptop and plugging in a USB mouse, the problem was still the same.


  • Right-click on “My Computer” on your desktop
  • At the top of the window that appears, left-click on the “Hardware” tab
  • Left-click on the “Device Manager” button
  • Look down the tree of Device items and left-click on the plus sign (+) to the left of “Mice and other pointing devices”
  • At this point, under the “Mice and other pointing devices” heading, you should see one listed item (driver) if you’re using just your touch-pad or one mouse
  • Right-click on that driver name – in my case it’s “Snaptics PS/2…”

From the menu that appears when you right-click on the mouse driver, choose “Update driver” by left-clicking on it.

  • Follow the update instructions
