Mouse clicking problem

[Tarq]

When trying to open a file by clicking on the left side of the mouse, it does not do this task, as it is necessary to open the menu by clicking on the right side, then log in. What is the solution

Try another mouse. Sounds like you are losing a button. They do wear out.

Here is a trick. Go ito your mouse settings and tell it that your are using it Left Handed. It will swap the button. See if the other button now works. If it does, get a new mouse.
