Enabling the mouse buttons when the Numlock feature is enabled.

The problem usually results from activating the mouse option in the “Easy Access” menu when using ALT codes on the Numlock keyboard.

After activating the “Use mouse buttons when Numlock is enabled” option on the “Mouse” tab of the Easy Access menu, several Windows users reported that the problem was completely resolved.

ALT keys are most often used when enabling or disabling push-to-talk features.

Most commonly, this problem occurs with VoIP applications, but other applications could be causing it as well.

Uninstalling the culprit app is as simple as following these steps:

  1. Open the Programs and Features dialog box by pressing Windows + R and typing “appwiz.cpl” in the textbox.
  2. The “Programs and Features” menu can be found under “Start Menu” and can be accessed by clicking on the “Programs” menu item in the top left corner.

  4. In step 3, you copied a special character. You can paste it by right-clicking -> Paste or pressing Ctrl + V.

Using third-party alternatives
